Adams Rite 4900-36-628 – Frequently Asked Questions

1) What else do I need to order to install an Adams Rite 4900 deadlatch?
The 4900 takes a mortise cylinder, which is not part of the latch, so specify that separately in the keyway your building is keyed to along with the correct cam and length for the stile. Mounting screws come with the latch. If the frame prep is not already there, add the 4901-02 4-5/8 inch strike. The faceplate is adaptable, which helps when the existing pocket in the stile is not a perfect match.
2) Do I have to order the Adams Rite 4900 handed, or can I flip it in the field?
Handing is field reversible on the 4900 deadlatch, so you are not stuck with what shows up. That said, it is ordered as LH or RHR and RH or LHR, so pick the one that matches the door and you skip the reversal step at the opening. Handy for a locksmith stocking a truck: one unit covers either swing after a bench change.
3) What does key-controlled bolt hold-back do on the Adams Rite 4900?
It lets you key the latchbolt back into the retracted position so the door stays free-entry, then key it out again for latched, exit-only operation. For a property manager running a lobby door that is open through business hours and locked after, this is the whole reason to buy the 4900 instead of a plain deadlatch: no propping, no separate hold-open device, and the staff member with the key controls it. The bolt is a 5/8 inch throw latchbolt with an auxiliary deadlatch pin that blocks loiding when the door is closed.
4) Can I use the Adams Rite 4900 deadlatch with an electric strike for access control?
Yes, and that is a common pairing. The 4900 works with the Adams Rite 7100 and 7400 UltraLine Series electric strikes, which is the route to take if you are adding card or intercom release to a storefront entrance. The deadlatch stays mechanical on the door side, the release happens at the frame, and the key hold-back still gives you a manual free-entry mode independent of the access system.
5) What is the difference between the Adams Rite 4900 deadlatch and the BEST 6KL deadlocking latch?
They are built for different door types and different certification levels. The Adams Rite 4900 is a Grade 1 heavy duty deadlatch for narrow stile aluminum and hollow metal doors, with a 5/8 inch throw stainless steel latchbolt, 1-1/8 inch or 1-1/2 inch backset options, and key-controlled bolt hold-back for two-way traffic control. The BEST 6KL is a Grade 2 deadlocking latch with steel construction in the 6K Series. If the opening is a narrow stile storefront door and the spec calls for Grade 1, the 4900 is the one that matches; if the job is written around the BEST 6K Series, the 6KL is the part in that family.
6) The spec on my drawing says ANSI Grade 1 deadlatch. Does the BEST 6KL meet that, or do I need the Adams Rite 4900?
The BEST 6KL is a Grade 2 deadlocking latch, so it does not satisfy a Grade 1 line on a drawing. The Adams Rite 4900 heavy duty deadlatch carries a Grade 1 rating and is built for 1-3/4 inch doors, which is what an institutional or MRO spec written to Grade 1 is asking for.
7) Will the Adams Rite 4900 fit a pair of doors with no mullion?
The 4900 latches into the jamb or into the inactive leaf, so for a pair you need the strike to suit. The 4901-02 4-5/8 inch strike is offered with radius profiles specifically for pairs of doors, which is what you want when the meeting stiles are rounded rather than flat. Confirm which profile matches your stile shape before the frame prep goes in.
8) How much room does the Adams Rite 4900 need inside the stile?
The latch body measures 7/8 by 5-13/16 inches plus depth, and the depth you need is driven by the backset you pick: 31/32, 1-1/8, or 1-1/2 inch. On a tight narrow stile the 31/32 inch backset is the one that fits where the deeper versions will not. Pull the old latch and check the pocket before you commit to a backset.
9) Is a deadlocking latch the same thing as an Adams Rite 4900 deadlatch for a storefront door?
Not for a narrow stile opening. The BEST 6KL is a steel-construction deadlocking latch in the 6K Series, a family built around cylindrical lock preps. The Adams Rite 4900 is a narrow stile deadlatch with a 7/8 inch by 5 13/16 inch case, 31/32 inch, 1-1/8 inch, or 1-1/2 inch backsets, a mortise cylinder, and field-reversible handing, and it works with 7100 and 7400 Series electric strikes. A locksmith replacing an existing narrow stile aluminum door latch needs the 4900 case dimensions to match the stile pocket.
10) I need a latch that can be held back with a key for daytime free entry. Will a BEST 6KL do that?
The BEST 6KL is described as a deadlocking latch, and key-controlled bolt hold-back is the specific feature of the Adams Rite 4900. The 4900 lets a key hold the latchbolt back so an opening runs free entrance during business hours and reverts to latching after, which is the function to order when a property manager wants one door open by day and secure at night.
11) What finishes does the Adams Rite 4900 deadlatch come in, and will they match my other storefront doors?
Three anodized finishes: 313 dark bronze, 335 black, and 628 clear. All three are offered across every backset and both handings, so a property manager standardizing a building can hold one finish and still cover different stile depths and swings. 628 clear is the usual match for mill-finish aluminum storefront, 313 for bronze-anodized frames.
