Don-Jo ST-261-DU – Frequently Asked Questions

1) Does the Don-Jo ST-261 have one latch hole or two?
One. The ST-261 is a single latch hole ASA strike, so it suits a standard lockset or mortise latch with a single latchbolt. If you're replacing a strike on a lock that has both a latchbolt and a separate deadbolt entering the frame, a single-hole strike won't accept both.
2) Will the ST-261 work on a pair of doors with no mullion?
No. The ST-261 mounts in the frame jamb on a single door opening. For a double door where the strike has to land on the inactive leaf, look at the Detex 92 Strike Kit, which is a double door strike kit supplied with tamper resistant fasteners.
3) Can I use the Don-Jo ST-261 to replace a worn strike without pulling the frame or lockset?
Yes, provided the existing prep is ASA. Because the ST-261 matches the standard ASA face at 4-7/8 x 1-1/4 inches with one latch hole, a worn or bent strike comes out and the new one goes back on the same two screws and into the same frame cutout. No new lockset, no frame work. Measure the old plate first: if it isn't 4-7/8 tall, the prep is something else.
4) What is the difference between a Trimco 1260P pipe adapter strike and a Don-Jo ST-261?
The Trimco 1260P is a pipe adapter strike from the 1260 Series - it is a strike only, made to adapt a latch to a pipe or tubular frame member rather than a conventional hollow metal jamb. The Don-Jo ST-261 is an ASA strike, 4-7/8 inches by 1-1/4 inches in 13-gauge ferrous steel with a single latch hole, sized for standard ASA strike preparation. Check the frame before ordering: a pipe or round column jamb calls for the 1260P, while a frame with an ASA cutout takes the ST-261.
5) Will a Detex 92 strike kit work in place of a Don-Jo ST-261 ASA strike?
No - they solve different openings. The Don-Jo ST-261 is an ASA strike for standard ASA frame prep, 4-7/8 inches high by 1-1/4 inches wide in 13-gauge ferrous steel with a single latch hole, so it drops into a frame already cut for ASA. The Detex 92 Strike Kit is a double door strike kit from the 90 Strike Series supplied with tamper resistant fasteners, intended for a pair of doors rather than an ASA-prepped single frame. If you are replacing a strike in an existing ASA cutout, the ST-261 is the part that matches the prep; if you are strikng the inactive leaf of a double door opening, the Detex 92 kit is the direction to go.
6) Is the ST-261 strike heavy enough for a high-traffic commercial entry?
13-gauge (.095) ferrous steel is the build, which is a heavy strike plate rather than a light residential stamping. Don-Jo rates the ST-261 for commercial use, and it holds up on office, school, healthcare, and multi-tenant openings that cycle all day. For a maintenance shop stocking spares, it comes in shelf packs of 30.
7) Is the ST-261 handed, or does one strike work on left and right hand doors?
Not handed. The ST-261 is a flat ASA strike with a single latch hole, and it installs the same way regardless of which way the door swings, so one part number covers left and right hand openings across a building. That's the reason it works as a standardizing item for a facility with mixed handing.
8) I need a tamper resistant strike for a security opening - is the Don-Jo ST-261 the right choice?
The ST-261 is a commercial ASA strike in 13-gauge ferrous steel with a single latch hole, supplied in BP brass plated, DU duronodic brown, SL silver and 622 matte black finishes. It does not come with tamper resistant fasteners. If fastener security is the deciding factor and the opening is a double door, the Detex 92 Strike Kit is supplied with tamper resistant fasteners as part of the kit. For a single ASA-prepped frame where the concern is latch engagement and durability rather than fastener attack, the ST-261 is the straightforward replacement.
9) What finishes does the Don-Jo ST-261 ASA strike come in?
Four: 622 matte black, BP brass plated, DU duronodic brown coated, and SL silver coated. On a frame where the strike is the only visible piece of hardware in the jamb, DU generally goes with dark bronze lever sets and SL with satin chrome or brushed nickel, so pick the one closest to the lockset already on the door.
10) Is the Don-Jo ST-261 strike steel, and will it rust on an exterior frame?
The substrate is ferrous, meaning steel rather than brass or stainless, at 13-gauge thickness. Ferrous strikes rely on their plating or coating for corrosion protection, so on an exterior or wash-down opening the coated finishes (DU duronodic brown, SL silver, or 622 matte black) are the sensible pick over bare-adjacent plating. For a coastal or pool environment, a non-ferrous or stainless strike is the better material choice.
