Demolition skid steer safety comes down to one question: what is between you and the debris? On a demo site, the answer should never be tempered glass. Glass fails all at once when concrete, brick, or rebar hits it, and it fails at the worst moment, while material is still coming down. A heavy-duty polycarbonate door with side window panels takes those same hits, stays in the frame, and keeps the cab sealed. That is why demo crews treat a poly enclosure as standard kit, not an upgrade.
Here is what a demo site actually throws at your machine, why glass is the wrong material for the job, and what a proper cab setup looks like.
What a Demo Site Throws at Your Cab
Demolition is the one job where the hazards aim back at you. On a grading or dirt job, most debris stays on the ground. On a demo job, you are pulling structures apart, and the structure fights back.
Think about a normal day of interior strip-out or teardown work:
- Falling material. Bricks, blocks, framing lumber, and drywall come down off walls and ceilings you are working under or beside.
- Kickback off the bucket and grapple. Concrete chunks bounce off hard floors and slab edges and come straight back at the cab.
- Rebar and wire. Cut or snapped rebar whips. Tension wire and cable let go without warning.
- Nails and fasteners. Every load of demo debris is full of them, and a bucket dumped at the wrong angle sends them flying.
- Dust. Concrete and plaster dust is constant. It cakes on windows, hides hazards, and fills an open cab all shift.
None of that is rare. It is the ordinary condition of the work. So the cab has to be built for it, and the weakest point of most cabs is the door opening.
Why Glass Is the Wrong Material Near Demolition
Tempered glass is fine at what it was designed for: spread-out pressure, wind, rain, and the occasional light knock. Demolition gives it the exact load it cannot handle, which is a hard strike on a small point.
When a chunk of concrete or the end of a rebar stick hits tempered glass, the glass does not crack and hold. It releases all at once and breaks into small pieces in an instant. Now three things are true at the same time. The cab is wide open. Debris is still moving. And you are sitting in the operator seat with glass in your lap.
There is a second problem that costs money instead of skin. A glass door that breaks on a Tuesday morning does not get replaced Tuesday morning. OEM dealers order glass in, and the machine either sits or runs open-cab on the dirtiest, most dangerous site it will ever work. Neither option is acceptable, and running with the door off can also get into your machine’s door safety switch or magnet setup. Do not improvise there. Call us at (800) 781-8000 and we will walk you through your machine’s setup.
We put the full material comparison, including where glass genuinely wins, in our polycarbonate vs tempered glass guide. The short version for demo work is below.
| On a demo site | Tempered glass | Lexan polycarbonate |
|---|---|---|
| Hard point impact (concrete, rebar) | Fails all at once | Flexes and absorbs the hit |
| Failure mode | Breaks into small pieces instantly | Stays in one sheet, stays in the frame |
| Cab after a strike | Open to everything still falling | Still sealed, keep working |
| Mid-job downtime | Wait on dealer glass | Typically none from a debris strike |
| Scratch resistance | Better | Needs basic care, rinse grit before wiping |
| Weight on hinges | Heavy | Lighter than glass |
Glass wins one line on that table. Polycarbonate wins the lines that keep you safer and keep the machine earning.
Polycarbonate Takes the Hit and Stays in the Frame
We build the Original Shatterproof Polycarbonate (Lexan) Door, and we were first to market with it. Lexan polycarbonate does something glass cannot do: it bends. A debris strike loads the sheet, the sheet flexes, soaks up the energy, and springs back. The door stays in the frame and the cab stays closed.
You do not have to take that on faith. Our owner Leighton put our 1/2 inch thick CAT D Series door on camera and hit it with a hammer, full swing, no edits. The door took it. You can see the footage and the whole story in our hammer test guide.
Every door is CNC-cut for your exact make and model, so it fits the opening the way the factory door did. No guesswork, no gaps at the edges for dust and fragments to find.
The Standard Demo Kit: Door Plus Side Panels
On demolition, debris does not politely arrive from the front. You work beside walls, under structures, and next to other machines. That is why the standard demo setup is the door plus side window panels, at $399 for the panels, closing off the side openings with the same polycarbonate thinking as the door.
With the door and side panels in, the cab is sealed. That does three jobs at once on a demo site:
- Impact protection on every side of your head, not just the front.
- Dust control. Concrete and plaster dust stays outside instead of in your eyes and lungs for eight hours.
- Temperature and noise. A sealed cab holds heat in January and cooler air in July, and it knocks down the constant bang and clatter of demo work so you finish the day less worn out.
Panel install is a simple hand-tool job. We cover it step by step in our side window panel install guide.
Two add-ons earn their keep on demo work. An electric wiper kit keeps the door clear when dust turns to paste in the rain. An LED light bar matters on interior strip-outs and short winter days, because on a demo site, what you cannot see is exactly what hurts you.
What’s in the Box
Every door ships as a complete kit. Open the crate and every supplied part is there, ready for the model-specific installation described in the included instructions:
| What’s included | Why it matters on demo work |
|---|---|
| Polycarbonate door | Heavy-duty Lexan, CNC-cut to your exact make and model |
| Door handle | Solid grip with gloves on |
| Locking latch with keys | Lock the cab overnight on an open site |
| Hinges | Matched to your model, no custom parts |
| Weather seal gasket | Seals dust out around the whole opening |
| All nuts, bolts, and washers | Nothing to source at the hardware store |
There is nothing else to buy and nothing else to source. If your machine never came with a factory door, we build a door frame kit for that too.
Fit for Your Machine, Including the Old Ones
We build precision-fit doors for ASV, Bobcat, CAT, Case, Gehl, John Deere, Kubota, Mustang, Manitou, New Holland, Takeuchi, and Terex. Doors run $1395 to $1795 depending on make and model. If you are running a Bobcat M Series on teardowns, or a CAT D3 pushing out slab, the exact door for it is already programmed into our CNC.
Demolition is also where old machines go to earn. A lot of demo buckets are swung by machines like the Case 1840 and 1845C, and nobody else builds enclosures for them anymore. We do. If your machine is not listed on our site, call or text (800) 781-8000 before you assume you are out of luck.
Demo-Day Cab Checklist
Run this before the first pass every morning. It takes two minutes.
- Door latched, gasket seated all the way around
- Side window panels in place and tight
- Door and windows rinsed before wiping, so grit does not scratch the Lexan
- Wiper working and washer fluid topped up
- Lights clean and aimed
- Loose tools out of the cab, so nothing flies inside if you take a hit
- Door safety switch or magnet setup untouched and working; if you have questions about yours, call us at (800) 781-8000
If the Worst Happens Anyway
Demolition is the job we had in mind when we set our warranty. Every door carries a limited lifetime warranty against door failure or breakage: one free replacement for life for the original owner, under normal conditions. Hardware is covered for 3 months.
And because a demo machine cannot sit for weeks, replacement doors ship the same way new ones do: UPS 3 Day Air, $150 flat, typically 3 business days (not guaranteed). That is the difference between protection you bought once and protection you keep for the life of the machine.
