How to Choose a Sliding Door Plunger Lock
Three questions get you to the right lock: plunger lock or push lock, what the doors are made of and how thick they are, and what key system it needs to match.
1. Plunger lock or push lock?
- Bypassing sliding cabinet or casework doors, on an N Series, R Series or SFIC key system: a sliding door plunger lock (300SD, 400SD or 722S).
- Bypassing sliding glass doors, using a small format IC core: the 723S cylinder housing. The core acts as the stop for the interior door.
- Tubular, Pagoda or disc tumbler key, mounted in a round hole: an FJM Security push lock (3776, 2610, 2612L, 1635 or 2615).
2. How thick is the door?
| Lock | Fit |
|---|---|
| 300SD, 400SD | Not listed on the data sheet: send us your door thickness and we'll confirm fit. Includes a bolt extender for varying gaps between bypassing doors. |
| 722S | Max. 1-7/8" door thickness; min. 5/8" for the TBM (through-bolt mount) version |
| 723S | Adjustable: ships with three screw lengths (7/16", 3/4" and 1") |
| Push locks | See the max. material thickness on each listing |
3. What does it need to key with?
- Olympus N Series: 300SD. Olympus R Series: 400SD.
- Small format IC (SFIC): 722S, 723S. Cores not included.
- Tubular, Pagoda or disc tumbler: the push locks.
Olympus Lock sells replacement keys and keeps custom keying records on file for adding locks later.

Frequently asked questions
Do I need a plunger lock or a push lock?
Pick by keying and mounting. Use a sliding door plunger lock (300SD, 400SD, 722S, 723S) to match an N Series, R Series or SFIC key system, or to replace C8142, 02291, 2S or 4S; each plunger lock works with a matching strike. Use an FJM Security push lock (3776, 2610, 2612L, 1635, 2615) for a tubular, Pagoda or disc tumbler key in a round mounting hole.
