Williams Brothers Heavy Duty Outdoor Series Cabinet (10LB 20LB and 30LB Capacity)

That is exactly what this one is for. The Heavy Duty Outdoor Series is fabricated from 16 gauge galvanneal steel, finished in baked red enamel over rust inhibiting phosphate treated steel, and the door carries weather resistive gasketing to keep water out of the box. The roof is sloped so runoff sheds instead of pooling on top, and the hinge is stainless steel so it does not rust in place. A standard indoor cold rolled cabinet in the same spot will bleed rust at the seams within a season.

No. The extinguisher is sold separately on the Heavy Duty Outdoor Series. What is in the box is the cabinet itself, weather resistive gasketing, the stainless steel handle, a full length stainless steel piano hinge with two roller ball catches, the safety lock, and the two decals. Size the extinguisher first, then order the matching cabinet: 10, 20, or 30 lb dry chemical.

Solid. The door is full metal, with no glass or acrylic vision panel, which is the trade off for an outdoor box that has to seal against weather. Because nobody can see the extinguisher through the door, the cabinet ships with a white "Fire Extinguisher" decal and a red "Pull Firmly to Open" decal so the location and the operation are marked. If your inspector or your facility standard requires the extinguisher to be visible, a full metal outdoor cabinet is not the right choice.

The Heavy Duty Outdoor Series comes with a safety lock, along with a stainless steel handle and two roller ball catches that hold the door shut against wind. That combination is the usual answer for a cabinet on an exterior wall, a parking structure, or a loading dock where an unsecured extinguisher goes missing.

Two things get chosen at order time. Decal orientation is required, and you pick None, Horizontal, or Vertical, matched to how the cabinet reads on the wall. Die cut lettering is optional and is where you match a facility standard: vertical die cut or horizontal die cut letters in red, white, or black, a Type A layout in red, white, or black, or the international extinguisher symbol in red or black. Facilities standardizing across many buildings usually fix one lettering choice and repeat it on every cabinet.

This cabinet uses a full length stainless steel piano hinge, which spreads the load of a heavy full metal door across the whole door edge instead of two or three points. On a door that gets yanked open in an emergency and sits in weather the rest of the year, that is what keeps the door from sagging out of the gasket line and letting water in. Stainless also means the hinge does not seize from corrosion the way a plated steel butt hinge does outdoors.
