Corbin Russwin 236L74-018-619 – Frequently Asked Questions

1) Will the Corbin Russwin 236L73-018 strike work with an ML20700 mortise lock?
Yes. The 236L73-018 is the ANSI straight lip strike specified for the L2000 latchbolt, and it is called out for the ML20700 x PWI1, ML20700 x PIP1, and ML20700 x PAC1 mortise locks. It handles the latchbolt only, so it is not the strike for a deadbolt-bearing function.
2) Is a 1-1/8 inch lip length long enough for my frame?
The 1-1/8 inch lip is measured from the strike centerline to the lip edge, and it needs to clear the frame stop so the latch rides onto the lip instead of catching the frame face. On a typical hollow metal frame with a shallow stop, 1-1/8 inch is the usual choice. Deep-stop frames, heavy wood casing, or applied trim call for a longer lip instead.
3) Do I need a separate strike if my mortise lock has a deadbolt?
Yes. The 236L73-018 is a latchbolt-only strike, so it has no deadbolt cutout. For a mortise function with both a latch and a deadbolt you need the combination latch-and-deadbolt ANSI strike for that lock instead.
4) What strike should I use for an aluminum storefront deadlatch instead of the Corbin Russwin 236L73-018?
The 236L73-018 is a latchbolt-only ANSI straight lip strike for Corbin Russwin ML20700 mortise locks, so it is not the part for a storefront deadlatch. Adams Rite offers the 4901 flush mount deadlatch strike with dust box and steel mounting plate and the 4902 deadlatch radius short strike with dust box, both intended for 4300, 4500, 4700 and 4900 Series deadlatches. Choose between the flush 4901 and the radius short 4902 based on the frame face you are prepping.
5) What finishes does the Corbin Russwin 236L73-018 strike come in?
Four finishes: 606 satin brass, 613 oil-rubbed satin bronze, 619 satin nickel, and 625 bright chrome. Pick the one already on the lockset and the hinges so the opening stays consistent, since 625 bright chrome reads noticeably brighter than 619 satin nickel on the same frame.
6) Is this strike handed, or does one part cover both left and right doors?
A straight lip ANSI strike is symmetrical top to bottom, so the same 236L73-018 serves either hand. Only the lip length and the finish need to be specified when ordering.
7) I need a reinforcing strike for a sliding door deadlock - is the Corbin Russwin 236L73-018 the right part?
No. The 236L73-018 is an ANSI straight lip latchbolt strike for Corbin Russwin ML20700 mortise locks. For sliding door deadlocks, Adams Rite lists the 4800 Series reinforcing strikes, which are built for that application.
8) Is this a suitable strike for standardizing school and hospital openings?
It is a commercial-grade component, and standardizing on one ANSI straight lip strike across openings running ML20700 mortise locks keeps stockroom part counts down. The 4-7/8 x 1-1/4 inch face is the same prep across those frames, so a single part number plus a matching finish covers the fleet.
