Adams Rite LEK7400-50 – Frequently Asked Questions

1) What does the Adams Rite LEK7400 lip extension kit actually do on a 7400 Series exit device?
The LEK7400 extends the strike lip on a 7400 Series device so it reaches from the vertical centerline of the door in the closed position out to the edge of the jamb. On aluminum storefront openings where the frame sits farther back than the standard lip covers, the latch has nothing to ride over and the door catches or fails to latch cleanly. The kit closes that gap by giving you a longer lip dimension without changing the device itself.
2) Will the LEK7400 fit an Adams Rite 8300 or 8800 exit device?
No. The LEK7400 is built for the 7400 Series and its lip geometry is specific to that device. Rim devices in the 8300/8400 family and top-of-door mounted 8800/8700/EX88 devices use their own strike arrangements, so a 7400 lip extension is not the part for them. Confirm the device stamped on the touchbar or chassis is a 7400 before you order.
3) I have narrow stile aluminum storefront doors where the exit device will not latch. Is a lip extension the fix?
If the device is a 7400 and the latch is missing the strike because the jamb edge sits beyond the reach of the standard lip, yes, that is exactly what the LEK7400 corrects. The 7400 Series is made for narrow stile aluminum doors, which is where jamb offsets vary the most from opening to opening. Measure centerline of the closed door to the jamb edge on that specific door before ordering, since one building can need two or three different sizes across its entrances.
4) Does adding a lip extension kit void the fire listing on a 7400 Series exit device?
The 7400 Series is UL 10C fire door listed and ANSI/BHMA Grade 1, and the LEK7400 is the manufacturer's own accessory for the series rather than a field modification. Using it in place of cutting or shimming a strike is how you keep a listed opening intact. If the opening is fire rated, install per the 7400 device instructions.
5) Does the LEK7400 lip extension have a handing, or does one part work on left and right hand doors?
Handing is not something you specify on the lip extension. The 7400 Series device itself is field reversible, and the kit is ordered by lip dimension only, from 1-3/8 through 3 inches. Get the measurement right and the same part works regardless of which way the door swings.
6) Can I use a lip extension kit on a 7400 exit device that works with a 7800 electric strike?
The 7400 Series is compatible with the 7800 Series electric strike, and 7400 devices are available with electric latch retraction. The LEK7400 addresses lip reach at the jamb, so on an electrified opening confirm the lip dimension against the strike as it is actually mounted in the frame, not against a bare jamb, before choosing a size.
