Don-Jo DL 11 630 – Frequently Asked Questions

1) What is a double lip strike and when do I need one instead of a standard single lip strike?
A double lip strike has a lip on both sides of the latch opening rather than one. It's what you use on a door that closes into a frame where the latch can approach from either side of the opening, or where a single lip would leave the frame edge exposed on the other side. The Don-Jo DL 11 is that style, in a 2-3/4 x 6-3/4 inch plate. If your existing strike has one lip and one flat edge, a double lip is not a drop-in swap for it, the frame prep and the way it sits on the jamb are different.
2) Will the Don-Jo DL 11 strike cover the mortise cutout left by my old strike plate?
The DL 11 plate measures 2-3/4 by 6-3/4 inches, so it covers a footprint that size on the jamb. Measure your existing plate and the exposed frame cutout first, if either dimension of what's there now exceeds 2-3/4 or 6-3/4 inches, the DL 11 will leave frame showing. It has a single latch hole, so it suits one latchbolt, not a lock with a separate deadbolt hole.
3) I need a strike for a pair of doors with no mullion, is the Don-Jo DL 11 the right part?
No. The DL 11 is a flat jamb strike with one latch hole, meant for a single latchbolt engaging a frame. A pair of doors without a mullion needs a strike made for that condition, the Detex 92 Strike Kit from the 90 Strike Series is a double door strike kit and includes tamper resistant fasteners. Order that instead of trying to make a jamb strike work at a meeting stile.
4) What is the difference between a double lip strike like the Don-Jo DL 11 and a pipe adapter strike?
The lip is what separates them. The Don-Jo DL 11 is a double lip strike in stainless steel, mounted flat to a conventional door frame so the lip covers the jamb edge and deflects the latch. The Trimco 1260P is a pipe adapter strike from the Trimco 1260 Series, and it is sold as the strike only - an adapter strike is shaped to mount to a round pipe or tube jamb rather than a flat frame face. Measure the jamb before ordering: flat frame stop takes the DL 11, a round post or pipe column takes the adapter strike.
5) Is the Don-Jo DL 11 strike heavy enough for a high traffic commercial entry?
It's built to 13-gauge (.095) thickness and rated commercial, which is the substance you want on a door that gets slammed hundreds of times a day. Thin residential strikes deform at the lip and the latch starts dragging, that's the failure mode heavy gauge material avoids. For a school corridor, a healthcare wing, or a multi-tenant entry, 13-gauge is the right spec.
6) Will a stainless steel strike hold up in a pool room, coastal building, or washdown area?
The DL 11 is stainless steel in a 630 satin stainless finish, and the construction is non-ferrous, so it resists the corrosion that eats plated steel strikes in humid or chemically loaded rooms. That makes it a reasonable pick for natatoriums, coastal exteriors, commercial kitchens, and wash-down corridors where a brass-plated strike would bloom rust within a season.
7) Does the Don-Jo DL 11 strike come in any finish besides satin stainless?
Satin stainless 630 is the only finish the DL 11 is built in, so if you're standardizing a building on 626 satin chrome or 613 oil-rubbed bronze, this one won't blend. On most commercial openings that's not a problem, 630 and 626 read close enough at the jamb that nobody notices from the corridor, but if the specifier called a finish on the drawing, 630 is what you're getting here.
8) My door latches into a round post rather than a flat frame, will this strike work?
A flat plate strike like the DL 11 needs a flat jamb face to sit against, it won't seat on a round post or pipe column. For that condition the part to look for is a pipe adapter strike, the Trimco 1260P from the 1260 Series is made specifically to adapt a strike to a pipe. Gate and railing openings are where this comes up most.
9) I need one strike plate, not a kit - does the Don-Jo DL 11 come as just the strike?
Yes. The Don-Jo DL 11 is the double lip strike itself, a stainless steel plate for commercial door hardware. The Trimco 1260P is likewise supplied as the strike only, so it is the comparable choice when the jamb is a pipe or tube section. The Detex 92, by contrast, is sold as a strike kit with tamper resistant fasteners, which is what you want only if the hardware on the pair of doors calls for that assembly rather than a single plate.
10) How many Don-Jo DL 11 strikes come in a pack?
The DL 11 ships in a shelf pack of 10. That's sized for a contractor doing a floor of doors or a property manager stocking a maintenance shop rather than a one-door repair, so if you're fixing a single jamb you'll have nine spares. For a building standardizing every opening on the same strike, the pack quantity is the point.
11) Can I use the Don-Jo DL 11 as a security reinforcement strike on an apartment entry door?
It's a latch strike, not a reinforcement wrap or a strike box. The 13-gauge material gives it real rigidity at the lip, but it's securing latch engagement, not reinforcing a split jamb or spreading force into the stud behind it. If the frame itself is the weak point, you want a strike box or a jamb reinforcer behind the plate, not a heavier face plate.
