Don-Jo SMEST-175-630 – Frequently Asked Questions

1) Will the Don-Jo SMEST-175 extended lip strike cover the gap on a door with an oversized frame reveal?
That is what the extended lip is for. The SMEST-175 measures 1-3/4 inches in width, and that width is taken from the center of the screw hole out to the end of the lip, so you get more lip projection past the frame face than a standard ASA strike gives you. Where the door sits deeper in the opening or the frame reveal is wide, the longer lip carries the latch across and keeps the latch from dragging on the frame edge. Height is 4-7/8 inches, the standard ASA strike height.
2) Will a 4-7/8 x 1-3/4 ASA strike drop into my existing hollow metal frame prep?
The SMEST-175 is cut to the ASA strike pattern at 4-7/8 inches high, which is the prep already punched into most commercial hollow metal frames, so on a frame prepped for ASA it goes in with no new cutting. The difference is the lip: at 1-3/4 inches from screw hole center to lip end it runs longer than a standard ASA lip, so check that the extra lip clears the frame stop and the door face before you set your screws.
3) I have a pair of doors with no mullion. Will this Don-Jo strike work?
No. The SMEST-175 is a frame-mounted ASA strike, it needs a jamb or a mullion to screw into, so it does nothing for a pair of doors that meet each other in the middle. For that opening you want a strike made for double doors, like the Detex 92 Strike Kit for double doors, which comes with tamper resistant fasteners.
4) What strike should be used when the latch has to catch on a pipe or round post instead of a door frame?
That is the Trimco 1260P Pipe Adapter Strike, sold as a strike only in Trimco's 1260 Series. It adapts the strike to a pipe rather than a flat frame face. The Don-Jo SMEST-175 will not do that job -- it is a flat extended lip ASA strike, 4-7/8 inches tall by 1-3/4 inches with the width measured from the center of the screw hole to the end of the lip, intended to be prepped into a conventional commercial frame. Pipe or round post opening: 1260P. Standard hollow metal or wood frame: SMEST-175.
5) Why does this Don-Jo ASA strike have two latch holes?
Two holes means it takes a lockset with both a latchbolt and a separate deadlatch or auxiliary bolt, the pair you find on most commercial cylindrical and mortise locks. The SMEST-175 is punched with 2 latch holes so the deadlatch plunger lands on the strike face rather than dropping into the latch opening, which is what keeps the latch from being loided. If your lock has a single bolt only, a one-hole strike is the cleaner match.
6) Is a non-ferrous strike worth it for an exterior or wash-down door?
Non-ferrous is the reason to pick it. The SMEST-175 body is non-ferrous material, so it will not rust the way a plated steel strike does when it takes weather, coastal air, or repeated cleaning chemicals. That makes it a reasonable call on exterior openings, pool and locker corridors, and healthcare or food service doors that get washed down. The body is 13-gauge (.095) so you are not trading strength for the corrosion resistance.
7) Is 13-gauge heavy enough for a high traffic entry door strike?
13-gauge works out to .095 inch of material, which is the heavy end for a face-applied strike and is what the SMEST-175 uses. On a door cycled hundreds of times a day, the latch hits the lip edge on every close, and thin strike stock is what bends and starts catching the latch. This one is built for commercial duty, not residential.
8) Can I use this ASA strike on an aluminum storefront door frame?
Generally not the right part. The SMEST-175 is the full 4-7/8 inch ASA pattern, which is too tall for the narrow jamb face on most aluminum storefront framing. Storefront openings normally take a short lip strike or a purpose-made adapter, and for those Trimco's 1260P pipe adapter strike from the 1260 Series is the kind of piece to look at. Save the SMEST-175 for hollow metal frames prepped to ASA.
9) Do I need a strike box or dust box with the Don-Jo SMEST-175?
The SMEST-175 is the strike plate itself, not a boxed assembly. On a hollow metal frame already prepped for an ASA strike the box is usually welded in behind the prep, so you are just replacing the visible plate. On a wood jamb, or a frame with no existing pocket, you need to mortise the jamb and add a box behind it so the latch and deadlatch have somewhere to go.
10) Is the SMEST-175 handed, or does one strike work on left and right hand doors?
Not handed. The SMEST-175 is a symmetrical ASA plate at 4-7/8 by 1-3/4 inches with 2 latch holes, so the same part serves left hand and right hand openings, and a property manager stocking spares only needs one part number across the building. What does change side to side is which way the lip faces once installed, and that is decided by how you set it, not by ordering.
11) For a high traffic commercial opening where the latch keeps missing the strike, is a heavier strike or a different strike type the right fix?
It depends on why it is missing. If the door is out of alignment on a normal frame and the latch is landing short of the lip, an extended lip strike like the Don-Jo SMEST-175 is the fix -- its 13-gauge (.095) non-ferrous body and extended lip profile carry the latch in and stand up to repeated engagement in commercial use. If instead the problem is a double door where the strike has to mount on the inactive leaf, that is the Detex 92 Strike Kit in the 90 Strike Series, which ships with tamper resistant fasteners. Confirm the opening type before ordering a heavier strike, because a thicker plate does not solve a double door condition.
12) Do the Detex 92 strike kit or the Trimco 1260P come in matte black or duronodic to match existing hardware?
Finish coordination is where the Don-Jo SMEST-175 stands apart from those two. The SMEST-175 is offered in 622 matte black, 630 satin stainless steel, and DU duronodic brown coated, so it can be matched to the rest of the trim on a fleet of doors. The Detex 92 Strike Kit is a double door strike kit in the 90 Strike Series and the Trimco 1260P is a pipe adapter strike in the 1260 Series -- both are selected for the opening condition they solve rather than as finish matches to an existing ASA strike. For a property manager standardizing appearance across openings, the three-finish SMEST-175 offering is the one that carries the match.
13) What finishes does the Don-Jo SMEST-175 strike come in, and which matches my existing hardware?
Three: 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. If the building is standardized on satin chrome or brushed stainless lever sets, 630 is the match and it is the most common commercial spec. DU is the dark bronze look that pairs with duronodic aluminum storefront and older bronze-anodized frames. 622 matte black suits black lever and exit hardware packages.
14) Can I standardize one strike across offices, classrooms, and back-of-house doors in my facility?
That is a fair use for the SMEST-175. It is a commercial strike on the ASA pattern, so it fits the same frame prep on every hollow metal opening in the building, and the 2 latch holes suit the deadlatch-equipped cylindrical and mortise locks typically used across those areas. Order it all in one finish, 630 satin stainless being the usual choice, and one part number covers the whole facility.
15) What is the exact Don-Jo part number for the 4-7/8 extended lip ASA strike?
Don-Jo model SMEST-175. The number carries the size: 4-7/8 inches high by 1-3/4 inches wide, that width taken from screw hole center to the end of the lip. Specify the finish with it, 622, 630, or DU, since the finish is the only ordering variable on the part.
