HES 5204 5200 Series Stackable Lip Extension

Four sizes of the 5204 lip extension are offered: 1/2 inch, 1 inch, 1-1/4 inch, and 3. Because they stack, you can also combine them if a single piece doesn't cover the gap you're dealing with, which is the usual reason someone reaches for this part on a retrofit frame.

That's exactly the condition a stackable lip extension addresses. When the door face sits out past the strike, the latch hits the edge of the lip instead of riding up it, and you get a latch that skips or a door that won't secure. The 5204 extends the lip out to meet the latch. Start with the smallest size that covers your measured gap, 1/2 inch, and stack up from there. If the misalignment is vertical rather than in and out, a lip extension won't solve it and the frame prep or strike position needs correcting instead.

No, those solve different problems. The HES 5204 is a stackable lip extension for 5200 Series electric strikes, sold in 1/2 inch, 1 inch, 1 1/4 inch and 3 inch sizes, so the lip reaches out to meet a latch that sits proud of the frame face. The Securitron SAM Surface Mount Kit Accessories are mounting parts for a SAM surface magnetic lock, which is a different locking method entirely and does not extend a strike lip. If the latch is not catching because of a gap at the frame, the lip extension is the part in that family; a surface mount kit will not close that gap.

A lip extension is a mechanical fit part, not an electrical one. The HES 5204 stacks onto a 5200 Series strike to extend the lip so the latch engages properly against the frame. If the strike is powered but not releasing, the issue sits upstream in power or signaling, and different parts address that: an Adams Rite 4605 regular transformer converts 115 VAC to 12/24 VAC with a 40 volt-amp output for strike power, and an RCI 9500/9501 mortise pin transfer rated 1.5A at 24VAC carries power across the door edge. Choose the 5204 when the latch is missing the strike, and a power or transfer part when the strike is not energizing.

Grade 1, and specified for commercial use. That's the top ANSI/BHMA durability tier, which is what an institutional or MRO buyer standardizing across a facility usually needs on the door hardware schedule. Since it's a lip extension riding on a 5200 Series strike, the grade tells you the accessory is built to the same commercial duty level as the openings these strikes go on.

No wiring. The lip extension is a mechanical piece that mounts to the strike body, it carries no coil, no solenoid, and no connections of its own. All the power goes to the 5200 Series strike itself. If you're pricing out a job, budget this as hardware only, not as part of the low-voltage run.

Yes, stacking is the point of the design. If a single 1-1/4 inch piece still leaves the latch short, add another. That's what separates this from a fixed-length lip, you're not forced to guess one size right on the first order, and a property manager dealing with frames that vary door to door can carry a couple of sizes and build to fit each opening.

The HES 5204 is an installation accessory that stacks onto a 5200 Series electric strike to lengthen its lip, and it is a Grade 1 commercial part. Securitron Glass Door Accessories are Grade 2 hardware built for glass door mounting, where there is no conventional frame to accept a strike lip. On a glass front where the lock is mounted to the door leaf rather than into a jamb, the glass door accessory line is the right family; the 5204 only applies where a 5200 Series strike is already installed in the frame and the lip needs to reach further.

They are add-ons to different parts of the opening. The HES 5204 is a stackable lip extension for 5200 Series electric strikes, a commercial Grade 1 installation accessory that adjusts how far the strike lip projects. A request to exit kit adds a switch to the exit device or lock so the system knows the door was used from the inside: the Command Access CRSREXKIT-ED is a field installable REX kit for Cal Royal 22/98 and Sargent 80 Series exit devices with an SPDT switch, and the Command Access REX-KIT-ML is a field installable REX kit for ML1-Series mortise locks. Ordering a REX kit will not change the strike lip geometry, and the 5204 provides no switching.

Depends what the opening needs. For power on the strike side, the Adams Rite 4605 transformer takes 115 VAC down to 12/24 VAC with a 40 volt-amp output. For request-to-exit signalling off a mortise lock, Command Access makes the REX-KIT-ML field installable kit, and the SCHLBMKIT-ML latchbolt monitor kit for Schlage L9000 mortise locks. If the strike is going into a glass or aluminum opening, look at the Securitron Glass Door Accessories. None of those replace the 5204, they round out the rest of the access control assembly.
