ABH A528SO-042-US32D – Frequently Asked Questions

1) Do I have to mortise the door edge to install an ABH A528 edge guard?
No routing required. The A528 is a non mortised overlapping guard, so it applies over the existing door edge and is fastened through, rather than being let into a milled recess. That is the practical difference from a mortised edge guard: you can retrofit an existing opening in place without pulling the leaf or bringing a router to site.
2) Can I put an ABH edge guard on a fire rated door without voiding the label?
Yes, within the ratings ABH publishes for the A528. It is UL fire rated for wood or plastic covered wood composite fire doors up to 1-1/2 hours, and for hollow metal fire doors up to 3 hours. That covers most cross corridor and stairwell openings in a commercial building. Above those durations on a wood leaf, it is out of scope.
3) Will adding an edge guard cause the door to bind in the frame?
That depends on the clearance you have now, and it is worth checking before you order. An overlapping guard adds .050 inch of 304 stainless on the edge and around onto the faces, which eats into the gap at the strike jamb and at the hinge side. ABH publishes a door clearance chart and a stainless steel edge guard clearance chart for exactly this check, plus installation templates for the A528. On a door already tight against the stop, the clearance chart is the deciding document.
4) Does the ABH A528 edge guard come with screws, or do I supply my own fasteners?
Fasteners are in the box: #6 x 5/8 inch Phillips flat head, undercut sheet metal screws. The undercut head is what lets the screw sit flush in the countersink of .050 inch material so nothing proud catches the frame as the door swings. Nothing else is needed to mount the guard itself.
5) Does the ABH A528 edge guard qualify for a Buy American Act project?
Yes, the A528 is BAA qualified, which is why it turns up on federal, municipal and public school specifications. If your submittal package needs domestic sourcing documentation for door protection hardware, this is a line item that clears it.
6) I am replacing an edge guard from another manufacturer. Will the ABH A528 match it?
ABH maintains a cross reference for its stainless steel edge guards that maps competitor model numbers to the ABH equivalent, so the substitution can be checked by part number rather than guessed at. Alongside it, the A528 installation templates give the hole pattern, which is what tells you whether the new guard picks up existing screw holes or gets fresh ones.
7) Do I need one edge guard per door or two, and does handing matter?
One guard per leaf, applied to the edge you are protecting, and it is normally the lock edge because that is where carts and traffic strike. On a pair of doors you order two. Handing is not an ordering variable here: the guard has no keying, no function and no lock prep, so the only choices to make are edge profile, square or bevel, and length. What does matter is edge profile, since a beveled leaf takes A528BO.
8) Will an edge guard fit over a door that already has an exit device or a mortise lock in it?
An overlapping edge guard runs the door edge and has to clear whatever is already there, so the length you order is set by the hardware on that edge. A mortise lock face, a rim device strike prep or a latch face interrupts the run, and that is why lengths like 42 inches exist alongside the 95 inch and 118.75 inch pieces: shorter sections protect the section of edge above or below the lock rather than fighting it. ABH publishes the A528 templates showing the guard profile and hole layout, which is the drawing to lay against your existing prep.
9) Is 304 stainless the right edge guard material for a kitchen, pool area or exterior door?
For wet and washdown areas, yes. The A528 is 304 stainless at .050 inch thickness, which resists the corrosion that takes out plated or painted steel guards in commercial kitchens, natatorium corridors and exterior service doors. The satin stainless finish also hides cart and dolly scuffing better than a bright finish on a high traffic leaf.
