Upgraded hardware — standard on every door

Get Close. Look At The Hardware.

Every part below is what actually ships on your door. Click any photo to open it full size and judge the machining, the finish and the fit for yourself.

Lift-and-slide lever handle set on a Gladiator aluminum sliding patio door — Lift-and-Slide Lever Handle Set (Optional)

Lift the lever and the panel rises onto its rollers and glides; drop it and the panel pulls down hard onto the seals and locks.

Premium D-shaped handle and lock set on a Gladiator sliding glass door — Premium D-Shaped Handle & Lock

A full-grip D-handle with an integrated lock set — sized for real hands and real panel weight, not a token pull.

Flush pull lock recessed into the stile of a Gladiator sliding door panel — Flush Pull Lock

Recessed flush pull for the interlocking stile, so panels sit tight against each other with nothing protruding.

04

Low-Profile Track, Hidden Drainage

Low-profile stainless sill with the drainage channel built in and hidden — water leaves, the step-over stays flat.

Optional threshold ramp bridging the sill track of a Gladiator sliding patio door — Threshold Ramp (Optional)

A low-angle ramp that bridges the sill for wheelchairs, strollers and carts — ordered with the door when you need a flush transition.

Adjustable track stop fitted in the sill of a Gladiator sliding patio door — Track Stop

A positive stop set into the track so panels land where they should instead of slamming the jamb.

Upgraded weather sealant strip on a Gladiator aluminum sliding door frame — Sealant Strip

The upgraded seal that runs the perimeter — the part that fails first on import doors and the reason they fog.

Cutaway of the thermally broken 6063-T5 aluminum frame of a Gladiator sliding door — Thermally Broken Aluminum Frame

6063-T5 extrusion with a true thermal break through the profile — not an aluminum skin over a softer core.

Optional nailing flange around a Gladiator sliding door rough opening — Nailing Flange (Optional)

Order it with a nail fin for new construction and the opening flashes like any other window unit.

All Doors Are Not Created Equal

What Makes Our Sliding Doors Different

Every upgrade below is included in the price — not an add-on, not an option. This is the difference between a door that lasts and a door you replace in two years.

Download Product Cut Sheet Flyer

PDF — Full specs, sizes & performance data

01

Upgraded Seal Package — Included

Seals are the first thing to fail on a sliding door, and failed seals are what causes hazing and fogging between the glass. Every door we build gets an upgraded seal package instead of the stock seal — better energy efficiency and no fogging years down the road.

Upgraded seals on every door, standard
Three-seal perimeter design with hidden drainage
Covered by our warranty — most brands cover seals 1–3 years, if at all

Cheap import brands: stock seals, short seal warranty. Read their warranty and you’ll see exactly what they skipped.

02

Upgraded Rollers & Bottom-Hung Track

Nothing on our doors is stock hardware. Our sliders are true bottom-hung — the full weight of the panels rides on precision rollers at the sill instead of hanging from the head, so the frame isn’t carrying the load.

Most manufacturers sell this as a paid upgrade. It’s standard on every sliding door we ship.

Upgraded precision rollers & bearings
Smooth-glide rail — large panels move with one finger
Commercial-grade handles and multipoint locks
All moving parts warrantied — most brands exclude them

03

100% Aluminum Construction

Not a wood core. Not vinyl wrapped in aluminum. All aluminum, start to finish — stronger, more stable, and it won’t rot, swell, or warp behind a wrap.

6063-T5 aluminum profiles, 2.2mm thick
92mm frame depth for large-span panels
SUS304 stainless steel track
Thermally broken frame

04

Upgraded Dual-Pane Glass — Included

Most imports ship 3–4mm single-thickness glazing to save cost. We use dual-pane 6mm upgraded, thermal-rated insulated glass on every door, included — which matters more on a slider, where panels are large and heavy.

Dual-pane 6mm glass
Argon-filled insulated unit
Low-E glass included
Less bowing and flex on wide panels

05

Low-Profile Track — Upgraded on Every Door

A lot of knock-off brands leave you with a giant step-over at the threshold. Every one of our doors is upgraded to low-profile track, included — and you have real options.

Low profile track (standard upgrade)
Recessed track — built-in drain system
High track available
Track ramps available
Hidden drainage on every track type

06

Custom Crated, Ready to Install

Every order ships in a custom-built wooden crate that costs us over $1,000 per order. Some brands won’t even mount the glass — they ship it loose to save on freight and hand you the labor.

Glass mounted at the factory
Pre-drilled and test-fitted before crating
Arrives ready to install — less labor, faster install

07

Private, Insured, Direct Delivery

Most brands hand your door to a large freight carrier that loads and unloads it ten times before it reaches you. That’s where damage happens — and slider panels are the largest, heaviest units we ship.

Private drivers, direct to you — costs us 4× more per order
Insurance taken out on every load
Never unloaded between the factory and your job site

08

A Real Warranty, Not a Gimmick

Look closely at those “10-year limited warranties” from cheap brands — they’re marketing gimmicks that exclude everything that actually breaks: frosting, rollers, seals, and moving parts.

Seals and moving parts included
Support and warranty handled here in the USA
15 year warranty on every door we build

Gladiator aluminum sliding glass patio door installed on a modern home

15Year Warranty

Built by contractors

Why We Build Them This Way

We got into this business as contractors. After installing multiple brands ourselves and watching unit after unit fail for the exact same reasons — seals, rollers, damage in transit, and a warranty process designed to deny the claim — we built a door that does it completely differently.

Everything Included Every upgrade included in the price, not sold back to you.

Install Issues Gone Install issues eliminated — pre-drilled, test-fitted, ready to hang.

Support In The USA We’re in the USA for after-sale support and warranty, not overseas.

Warranty That Pays We warranty what actually breaks — seals and moving parts included.

Our doors are not stock for a reason. They’re all aluminum for a reason. A door should not need to be replaced two years down the road — don’t buy a cheap door and get forced into buying a second one within a year.

Gladiator Window & Doors

Your home doesn’t end at the wall.It ends where you decide.

More room · More light · More life

Why our sliding doors

Built Different, Down to the Detail

Ten places where ours separate from what you'll find at big-box retailers and discount importers.

01

Cascade & Bi-Parting Configurations

Two, three, four or six panels — cascading to one side or parting from the centre — configured around how your opening actually gets used. Big-box and discount importers hand you one fixed layout and call it a choice.

02

Customizable Color Options

Choose from multiple premium colors instead of being limited to standard black or white. Your home deserves better than one-size-fits-all options.

03

Upgraded Energy-Efficient Seals

Superior seal packages on every door, delivering better insulation and lower energy costs year-round. Cheap doors use the worst seals available, costing you in utility bills — and hazing between the glass within a few years.

04

Low-Profile Track System

Upgraded low-profile tracks give smooth operation and a cleaner threshold compared to the bulky track systems on discount models. Recessed, high track and ramp options are all available.

05

Complete, Ready-to-Install System

Glass arrives professionally mounted in the frames with all hardware included, pre-drilled and test-fitted. Many brands make you buy hardware separately, mount the glass yourself, and fight missing parts on install day.

06

Real Warranty Protection

Look closely at those "10-year limited warranties" from cheap brands — they exclude everything that actually breaks: frosting, rollers, seals and moving parts. Ours covers what matters.

07

Premium Aluminum Construction

All aluminum — no wood core, no vinyl wrapped in aluminum. Thicker profiles and true double-pane systems for better soundproofing, strength and longevity. Cheap brands use the thinnest metal possible, which bends, warps and hazes within months.

08

Screen & Blinds Systems

Add screens or integrated blinds with any door, built into the same system instead of bolted on afterward.

09

15 Year Warranty

Every door we build is backed for 15 years, with support handled here in the USA — not a phone tree overseas that outlasts the claim.

10

Code-Compliant, Permit-Ready

Many discount brands don’t meet building codes. Our doors can be installed with proper permits, and we supply the spec sheets, CAD files and NFRC data your plan reviewer asks for.

The True Cost Of “Savings”

Saving 30–40% on a cheap door might seem attractive today, but when you’re replacing it in two years due to hazing between glass panes, malfunctioning hardware or structural failure — plus paying another contractor for reinstallation — you’ll spend far more than if you’d chosen quality from the start.

Factory-Direct Advantage

We do not accept orders through the website

The part nobody talks about

A Door Is Only As Good As How It Arrives

Most damage never happens on the job site. It happens on a truck, on a forklift, in a cross-dock, somewhere between the factory and your driveway. Open-slat pallets wrapped in plastic are the industry norm. We don’t ship that way.
