Don-Jo SMEST-158-630 – Frequently Asked Questions

1) Will the Don-Jo SMEST-158 extended lip strike cover an offset or misaligned latch?
That is what the extended lip is for. The SMEST-158 is an extended lip ASA strike, and the lip runs past the frame face so a latch bolt that sits proud of the jamb or lands slightly off center still gets captured. The 1-5/8 inch width is measured from the center of the screw hole out to the end of the lip, so that figure tells you how far the lip reaches on your frame. Measure from your existing screw line to where the latch actually contacts, and if it is inside 1-5/8 inches the lip picks it up.
2) What size cutout does the Don-Jo SMEST-158 ASA strike need in the frame?
The SMEST-158 is a 4-7/8 x 1-5/8 inch ASA strike, so it drops into the standard ASA (T-strike) prep already cut into most commercial hollow metal frames. The 4-7/8 inch dimension is the strike height, the 1-5/8 inch is measured from the center of the screw hole to the end of the lip. If the frame was prepped for a standard 4-7/8 inch ASA strike, the screw centers and the cutout line up; you are only changing the lip projection.
3) Can I use the Don-Jo SMEST-158 on a pair of doors with no mullion?
No. The SMEST-158 is a single ASA strike that mounts in the frame jamb, so it serves one leaf latching into a frame or a mullion. For a pair of doors where the strike has to be secured against tampering at the meeting point, the Detex 92 Strike Kit is built for double door applications and comes with tamper resistant fasteners.
4) Is the Detex 92 strike kit an equivalent replacement for a Don-Jo SMEST-158 ASA strike?
No, they solve different problems. The SMEST-158 is an extended lip ASA strike in non-ferrous 13 gauge construction, mortised into the frame of a single opening so the latch bolt of a standard commercial lock catches cleanly. The Detex 92 Strike Kit is a double door strike kit from the Detex 90 Strike Series, supplied with tamper resistant fasteners for a pair of doors where there is no frame jamb on the strike side. If you are working a single opening with a standard ASA frame prep, the SMEST-158 is the part; a double door application with no fixed jamb is what the Detex 92 kit addresses.
5) What strike do I use if the door has a pipe or round column instead of a flat jamb?
The Trimco 1260P is a pipe adapter strike, sold as a strike only, from the Trimco 1260 Series, and it is the part intended for a pipe or tubular frame member rather than a flat jamb face. The Don-Jo SMEST-158 is a flat extended lip ASA strike, 4-7/8 inches high by 1-5/8 inches wide with the width measured from the center of the screw hole to the end of the lip, and it seats against a flat frame face. On a round section, go to the 1260P; on conventional flat frame stock, the SMEST-158 extended lip gives you room for a latch bolt that sits off center.
6) Is the Don-Jo SMEST-158 strike heavy enough for a high traffic commercial door?
It is built at 13 gauge (.095) thickness and rated for commercial use, which is what keeps the lip from bending back after repeated latch strikes on an entry or corridor door. Thin residential strikes deform at the lip first; the .095 material is where the durability comes from here.
7) Will a Don-Jo SMEST-158 strike corrode or discolor on an exterior or coastal door?
The SMEST-158 is non-ferrous, so it will not rust the way a plated steel strike does when water sits in the frame pocket. That makes it the safer pick for exterior openings, pool and locker room doors, or any wash-down area where a ferrous strike bleeds rust down the jamb.
8) What finishes does the Don-Jo SMEST-158 ASA strike come in, and which matches my existing lockset?
Three: 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. If the building is standardized on satin stainless levers and exit devices, 630 is the match, and it is the most common commercial finish by a wide margin. 622 pairs with matte black hardware, and DU matches dark bronze anodized aluminum storefront and entrance doors.
9) Do I need an extended lip strike or a standard ASA strike?
Go extended lip when the door is undercut relative to the frame, the frame is set back, or the latch is not seating square on a standard lip. That is the SMEST-158's job. If your door and frame are flush and the latch centers on the standard lip, a plain ASA strike does the same work with less metal sticking out into the opening. The extended lip does project further into the door swing, so check it clears the door edge and any weatherstrip before you commit.
10) What is the difference between the Don-Jo SMEST-158 and a Trimco 1260P pipe adapter strike?
Different jobs. The SMEST-158 is an extended lip ASA strike for a standard hollow metal frame prep. The Trimco 1260P is a pipe adapter strike, made to mount where the latch has to strike a round post rather than a flat jamb. If you are latching into a pipe or tube column, the ASA strike has nothing flat to sit against and the 1260P is the part you want.
11) I need one strike type standardized across a building. Which of these covers the most openings?
For a facility standard on conventional single openings, the Don-Jo SMEST-158 is the broader fit: it is a commercial extended lip ASA strike with 2 latch holes to suit a range of commercial latch bolt configurations, in 622, 630 and DU finishes so it can be matched to existing trim across a building. The Detex 92 Strike Kit and the Trimco 1260P are application-specific by comparison, the first a double door kit in the Detex 90 Strike Series and the second a pipe adapter strike in the Trimco 1260 Series. Most facilities standardize on the ASA strike and stock the specials only for the openings that need them.
12) Why does the Don-Jo SMEST-158 strike have two latch holes?
The two latch holes let one strike serve more than one latch bolt position, which is why it fits a range of commercial locksets rather than a single prep. Check which hole your latch centers on before you fasten the strike down, then set the lip so the bolt enters cleanly without dragging on the edge.
13) Can I standardize the Don-Jo SMEST-158 across all the doors in my building?
Yes, wherever the frames carry a standard 4-7/8 inch ASA prep, which covers most commercial hollow metal openings. Ordering one finish, most often 630 satin stainless, gives you a single strike to stock for offices, classrooms, healthcare corridors, retail, and multi-tenant residential. The non-ferrous construction means the same part goes on exterior openings without a separate corrosion-resistant SKU.
14) Does the Don-Jo SMEST-158 come with security fasteners like the Detex 92 kit?
The Detex 92 Strike Kit is supplied as a kit with tamper resistant fasteners, which is what you want where the strike side is exposed and someone can get a driver on it. The Don-Jo SMEST-158 is the strike plate itself, non-ferrous at 13 gauge (.095) for corrosion resistance and rigidity under repeated latch engagement. If tamper resistant fastening is a requirement of the opening rather than a preference, specify the hardware that carries it; if the requirement is a durable ASA strike in a protected frame, the SMEST-158 covers it.
