ABH A548SM-42-US32D – Frequently Asked Questions

1) Will the ABH A548SM edge guard fit a 1-3/8 inch door?
No. The A548SM and A548BM are built for 1-3/4 inch doors only, and the mortised channel is cut to that thickness, so a 1-3/8 inch leaf will not seat properly. If your openings are the older 1-3/8 inch interior thickness, you need an edge guard made for that thickness instead.
2) Can an edge guard with an integral astragal be used on a fire rated door?
The A548SM and A548BM carry a UL fire rating: wood or composite fire doors up to 1-1/2 hours, and hollow metal fire doors up to 3 hours. That covers most rated corridor and stair openings. Note the split, a wood door assembly is limited to the 1-1/2 hour label, so a 3 hour rating only applies where the leaf is hollow metal.
3) Does the ABH A548 edge guard protect the latch from being jimmied?
That is what the integral astragal is for. The A548SM and A548BM wrap three sides of the door edge and carry a built in astragal that covers the gap at the latch, so a pry bar or shim cannot reach the latchbolt directly. It is a common retrofit on multi-tenant and institutional openings that have already been forced once, and it works without changing the lock or the strike.
4) Does the ABH A548 edge guard meet Buy American Act requirements?
Yes, the A548SM and A548BM are BAA Qualified, which is what a government, municipal or federally funded institutional job usually needs on the submittal. The material is 304 stainless steel at .050 inch thickness.
5) Do I need to order screws separately for the ABH A548 edge guard?
No, fasteners ship with it. Each A548 edge guard comes with #6 x 5/8 inch Phillips flat head undercut sheet metal screws. The undercut head sits flush in the countersink so nothing proud catches the frame as the door closes. You will want a drill and the ABH template to lay out the hole pattern, but no separate hardware purchase.
6) Should I use a mortised edge guard or a surface applied one on a door that keeps getting kicked?
A mortised guard like the A548 is cut into the door edge, so the stainless sits nearly flush and there is no exposed lip for a pry bar to catch, and the integral astragal closes the latch gap at the same time. A surface applied edge guard is easier to install on a door already hung and does not require mortising, but it adds thickness on the face and leaves an edge. On a repeatedly forced opening the mortised version with the astragal is the one that addresses the latch itself. The tradeoff is labor: the A548 needs the door edge routed to accept it.
7) I have an edge guard from another manufacturer on my doors, can I match it with an ABH A548?
ABH publishes a cross reference for its stainless steel edge guards that maps competitor model numbers to the equivalent ABH part, so the A548SM or A548BM can be matched against what is already installed. Before ordering, confirm three things about the existing guard: the door is 1-3/4 inches thick, the edge is square or beveled to match SM or BM, and the length falls within the 120 inch maximum.
8) What finish does the ABH A548 mortised edge guard come in?
Satin stainless steel, in every length and both edge types. That is US32D in the finish codes a locksmith or spec writer uses, and it matches the satin stainless hinges, push plates and exit device trim already on most commercial openings, so a building standardized on 630/US32D hardware stays consistent.
9) Is the ABH A548 edge guard suitable for a healthcare or school corridor door?
It is a commercial grade part built for exactly that traffic. 304 stainless at .050 inch resists corrosion and the cleaning chemicals used in healthcare, and the fire rating covers rated corridor doors, up to 1-1/2 hours on wood or composite and up to 3 hours on hollow metal. Common applications include educational, healthcare, government, industrial and multi-tenant residential openings.
10) Does the ABH A548 edge guard interfere with the lock or require rekeying?
No keying is involved. The A548 is an edge protection channel with an astragal, not a locking device, so it does not touch the cylinder, keyway or key system. It mounts to the door edge around the existing latch prep, which is why it works as a retrofit on doors whose hardware you want to leave alone.
