Installation & Operation

  1. Review manufacturer specifications and verify door preparation requirements including door thickness compatibility with 1-3/4" doors and narrow stile construction.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and determine optimal paddle height between 30 to 44 inches above finished floor.
  3. Prepare door by drilling required holes and routing as specified, including 1/2" diameter hole in threshold for bottom bolt strike.
  4. Install flanged post strike on header with generous location adjustment to accommodate door misalignment, sag, and bumpers as needed.
  5. Mount paddle assembly and rod mechanism, adjusting rod length for proper door height and paddle positioning.
  6. Test paddle operation to verify 1-1/2" stroke function, deadlock engagement of both top and bottom bolts, and smooth door operation. Configure paddle dogging feature if free-swinging operation is desired. Refer to manufacturer documentation for complete installation details and troubleshooting.

Adams Rite 4781-021-628 – Frequently Asked Questions

1) Will the Adams Rite 4781 deadlatch let me keep both leaves of a pair of doors active without flush bolts?
That is exactly what the 4781 two-point deadlatch is for. It latches into the header and into the threshold, so the inactive leaf of a pair of out-swinging narrow stile doors stays active and can be opened by pushing the paddle. It replaces the usual arrangement where one leaf is pinned shut with conventional flush bolts. Both leaves have to be out-swinging narrow stile construction for it to apply.
2) Do I have to specify handing on the Adams Rite 4781 paddle deadlatch?
Yes, handing matters. The 4781 is ordered as either Push to Left or Push to Right, and that choice sets which way the paddle swings when someone pushes through. Stand on the egress side and note which direction the paddle needs to travel before you place the order. All four finishes are offered in both operations.
3) What is the difference between the standard rod and top rod only option on the 4781?
Standard rod gives you the full two-point latching, top bolt into the header and bottom bolt into the threshold. Top Rod Only drops the bottom bolt, so the door latches at the head alone. Pick top rod only where you cannot drill the threshold or where a floor bolt would be a trip or drainage problem; pick the standard rod anywhere you want the leaf secured at both ends. Both options are available in all four finishes and in both push directions.
4) Does the Adams Rite 4781 come with a cylinder, and what kind do I need to order?
No cylinder is supplied with the 4781. It takes a standard Adams Rite MS cam mortise cylinder, so budget one per device and get it keyed into your existing system before the install. If you are standardizing a building, order the cylinders on the same keyway as the rest of the storefront doors.
5) What door prep does the 4781 two-point deadlatch need in the threshold and header?
Two things beyond the door itself. The threshold needs a 1/2 inch diameter hole for the bottom bolt strike, and the header takes a flanged post strike. The post strike has generous location adjustment built in, which is what lets you absorb door sag, misalignment, and bumper stand-off on an existing opening rather than re-hanging the leaf. Use the manufacturer template to lay out the paddle and rod holes, and set rod length to the door height during the mount.
6) Can a BEST 6KL latch be used in place of an Adams Rite 4781 on a pair of narrow stile aluminum doors?
No, they solve different openings. The Adams Rite 4781 is a two-point deadlatch that latches into the header and the threshold, which is what keeps both leaves of a paired out-swinging narrow stile door active without conventional flushbolts, and it carries a Grade 1 rating with a paddle mounted anywhere from 30 to 44 inches above finished floor. The BEST 6KL is a Grade 2 deadlocking latch of steel construction in the 6K Series, latching at a single point into the jamb. On a pair of doors the 6KL secures the active leaf only, so the inactive leaf still needs its own bolting. Where a paired narrow stile entrance has to have both leaves operable from the paddle, the 4781 is the part that does it.
7) Can I tie the Adams Rite 4781 into a card reader or access control system?
Yes. The 4781 works with Adams Rite electric strikes, so you can run it on an access control system with the reader releasing the strike at the header. The device itself is mechanical, the cylinder is separate, and you order the strike to suit the frame.
8) Can the 4781 paddle be held in the retracted position for a business day?
Yes, the 4781 has a paddle dogging feature. Set it and the leaf swings free with the bolts held retracted, which is what you want during open hours on a retail or office entrance; release it to put the door back on two-point latching at close. The paddle itself has roughly a 1-1/2 inch stroke in normal operation.
9) Is a deadlocking latch like the BEST 6KL an alternative to the Adams Rite 4781?
They solve different problems. The BEST 6KL Series is a Grade 2 deadlocking latch of steel construction, a single-point latch for a conventional door. The 4781 is a two-point device that bolts into the header and threshold to keep the second leaf of a narrow stile pair active. If your opening is a single door, a deadlocking latch is the simpler buy; if it is a pair of aluminum doors and you want both leaves usable, the 4781 is the one that does that job.
10) Will the Adams Rite 4781 work on a hollow metal or wood door, or is it aluminum only?
It is engineered for narrow stile aluminum doors, but hollow metal and wood door options exist in the 4781 range, so specify the door material when you order. The 1-3/4 inch thickness requirement holds regardless of material.
11) What latch should I order for a single door opening instead of the Adams Rite 4781?
A single-leaf opening does not need two-point latching, so the BEST 6KL is the simpler fit. It is a Grade 2 deadlocking latch built in steel from the 6K Series, latching at one point into the strike. The Adams Rite 4781 is built around a paddle and a vertical rod that deadlock a top bolt into a header strike and a bottom bolt into a hole drilled in the threshold, hardware that only earns its keep when both leaves of a pair have to stay active. On a single door that rod, header strike and threshold prep are work you would be doing for no gain, and the 4781 is also handed, ordered push to left or push to right.
12) What finishes does the Adams Rite 4781 paddle deadlatch come in?
Four ordering finishes: 313 dark bronze anodized, 335 black anodized, 628 clear anodized, and 626 satin chrome. The three anodized options are the ones that match typical aluminum storefront framing, so if you are matching existing entrances on a property, take the finish from the frame rather than from the other door hardware. Every finish is offered in both push directions and with either rod option.
