Adams Rite 4911W-35-101-628 – Frequently Asked Questions

1) What backset do I need to order for an Adams Rite 4911W deadlatch?
Measure from the edge of the stile to the centerline of the cylinder hole on the door you are prepping. The 4900 Series deadlatch is offered in 31/32 inch, 1-1/8 inch, and 1-1/2 inch backsets, so match the existing prep rather than reworking the stile. Narrow stile aluminum entrances most often land on 31/32 or 1-1/8; 1-1/2 shows up on wider stiles.
2) Do I have to specify handing on an Adams Rite 4900 deadlatch, or can I change it in the field?
Handing is field reversible on the 4900 deadlatch, and the latchbolt can be flipped without special tools. You still pick a handing when ordering, either LH or RHR, or RH or LHR, so order the hand you have and reverse it on site only if the door turns out opposite.
3) Will the Adams Rite 4900 deadlatch latch into my existing strike?
The bolt throws 5/8 inch, with a latchbolt measuring 5/8 x 1 x 5/8 inches, so the existing strike pocket has to accept that. Adams Rite pairs it with the 4901-02 4-5/8 inch strike, and strikes are offered mortised in 2-5/8 inch and 4-5/8 inch, in flat profiles for standard jambs and 4 inch or 4-1/2 inch center hung jambs, plus a radius profile for standard stiles. If your jamb prep does not match one of those, order the latch with the strike that suits the frame.
4) Does the Adams Rite 4900 deadlatch come with a cylinder?
No cylinder is included. The 4900 deadlatch takes a mortise cylinder, ordered separately, so you can key it into whatever system the building already runs. Mounting screws come with the latch.
5) Will an Adams Rite 4900 deadlatch work with an electric strike for access control?
It is compatible with Adams Rite 7100 and 7400 UltraLine Series electric strikes, so it drops into a card reader or buzzer setup on an aluminum entrance without changing the latch.
6) What is the difference between the Adams Rite 4900 Series deadlatch and the BEST 6KL deadlocking latch?
They are built to different performance grades and for different door types. The Adams Rite 4900 Series is a Grade 1 heavy duty deadlatch for narrow stile aluminum and hollow metal doors, with a 5/8 inch latch throw, a 5/8 inch x 1 inch x 5/8 inch latchbolt, and 1-3/4 inch door thickness, operated by a mortise cylinder. The BEST 6KL is a Grade 2 deadlocking latch with steel construction. If the opening is a narrow stile aluminum storefront door and the specification calls for Grade 1, the 4900 Series is the one that matches; the 6KL is the choice where a Grade 2 deadlocking latch is acceptable.
7) Can an Adams Rite 4900 deadlatch be used on a pair of aluminum doors with no mullion?
Yes. The 4901-02 4-5/8 inch strike is available with radius profiles specifically for pairs of doors, and there is a radius strike option for standard stiles. That is how you handle an inactive leaf edge instead of a jamb.
8) Can I set an Adams Rite 4900 deadlatch to stay unlocked during business hours?
That is what the key-controlled bolt hold-back does. Turn the key to hold the bolt retracted and the door swings free for daytime traffic; release it and the latch goes back to exit-only, latching on close. Useful on a storefront or lobby leaf that has to be open all day and secure after hours.
9) Is the Adams Rite 4900 deadlatch secure against someone slipping the latch with a card?
There is a stainless steel auxiliary deadlatch pin that blocks loiding, so the bolt cannot be shimmed back once the door is closed and the pin is depressed against the strike. The latchbolt itself is stainless with a self-sealing design, and the latch is Grade 1 for heavy duty commercial traffic.
10) How much stile do I need for an Adams Rite 4900 deadlatch faceplate?
The case measures 7/8 x 5-13/16 inches by depth, and the 7/8 inch dimension is what sits in the stile face. The 4900 is made for narrow stile aluminum and hollow metal doors, so it fits stiles too slim for a conventional mortise lock. The radius weatherstrip faceplate version follows the curved stile profile on doors that carry weatherstripping in the edge.
11) Can a BEST 6KL be used in place of an Adams Rite 4900 deadlatch on an aluminum storefront door?
Treat them as different products rather than direct swaps. The Adams Rite 4900 Series is dimensioned for narrow stile work: a 7/8 inch x 5-13/16 inch case, backsets of 31/32 inch, 1-1/8 inch, or 1-1/2 inch, field reversible handing, and mortised strikes in 2-5/8 inch and 4-5/8 inch sizes with flat and radius profiles to suit the stile and jamb. The BEST 6KL is a Grade 2 deadlocking latch with steel construction and belongs to the 6K Series. On a narrow stile aluminum door already prepped for a 4900, matching the existing backset and strike prep is what keeps the retrofit to a straight exchange.
12) What finishes does the Adams Rite 4900 deadlatch faceplate come in to match my existing storefront?
Three anodized finishes: 628 clear anodized, 313 dark bronze anodized, and 335 black anodized. Those are the three standard aluminum storefront colors, so pick the one matching the door frame rather than the door hardware.
13) Can I standardize on the Adams Rite 4900 deadlatch across a building's exterior aluminum doors?
It is a commercial, heavy duty, Grade 1 latch, and every unit takes the same mortise cylinder, so one keying system covers the fleet. The variables you match per opening are backset (31/32, 1-1/8, 1-1/2 inch), handing, finish, and the strike that suits each jamb. Case and function stay the same across all of them.
