Adams Rite 4913-25-IB – Frequently Asked Questions

1) What backset do I need for an Adams Rite 4913 deadlatch on a narrow stile aluminum door?
The 4913 deadlatch lock body is built in three backsets: 31/32 inch, 1-1/8 inch, and 1-1/2 inch. Measure from the door edge to the centerline of the cylinder hole on the existing prep and order the one that matches, because the backset is fixed in the case and cannot be adjusted in the field. On aluminum storefront, 31/32 and 1-1/8 cover most narrow stile preps; 1-1/2 is the wider one.
2) Is the Adams Rite 4913 deadlatch handed, and how do I pick left or right?
Handing matters here. The 4913 is ordered as either LH or RHR, or RH or LHR. Stand outside the opening: a door hinged on your left that pulls toward you is left hand, and the same leaf hinged right and pushing away is right hand reverse, which is why those two share one part. Get it wrong and the latch bevel faces the wrong way and will not deadlatch against the strike.
3) What cylinder do I order with an Adams Rite 4913 deadlatch, and is it included?
The cylinder is separate. The 4913 takes a mortise cylinder, 1 inch length, with the Adams Rite MS cam. Order that cylinder in the keyway your building is already keyed to, and it can be keyed into the existing master system. Mounting screws come with the lock body.
4) Will the Adams Rite 4913 latch engage my existing storefront strike?
The latchbolt is solid brass measuring 5/8 x 1 x 5/8, with a 5/8 inch throw. That is the standard narrow stile projection, so it drops into a jamb strike or an Adams Rite electric strike cut for a 5/8 inch throw deadlatch. If your existing strike lip was cut for a deeper bolt, the pocket depth is fine but check the vertical position against the new case, which runs 7/8 x 5-13/16 inches by depth.
5) What is the difference between the Adams Rite 4913 deadlatch and the BEST 6KL deadlocking latch?
Both are steel deadlocking latches for commercial openings, but they are graded and prepped differently. The Adams Rite 4913 is a Grade 1 heavy duty deadlatch lock body sized for narrow stile aluminum doors, with a 5/8 inch latch throw, a 1-3/4 inch door thickness, a 7/8 inch x 5-13/16 inch case, and mortise cylinder operation. The BEST 6KL is a Grade 2 deadlocking latch of steel construction in the 6K Series. If the opening is a narrow stile aluminum door taking a mortise cylinder, the 4913 is the body cut for it; the 6KL is the choice where a 6K Series latch is what the door is already prepped around.
6) Is a BEST 6KL deadlocking latch an acceptable substitute for an Adams Rite 4913 on a spec that calls for Grade 1?
No. The BEST 6KL is a Grade 2 deadlocking latch, while the Adams Rite 4913 deadlatch is Grade 1. On a facility standard or a drawing written to ANSI/BHMA Grade 1, the 4913 meets the line and the 6KL does not. The two are both steel deadlocking latches, so they read as interchangeable on a takeoff, which is exactly where the grade difference gets missed.
7) Can I use the Adams Rite 4913 deadlatch for card access or a buzz-in entry?
Yes, as the mechanical half. The 4913 pairs with Adams Rite electric strikes, so the access control sits in the frame and the lock body stays a plain deadlatch. That is the usual way a storefront entry gets put on a reader or a front desk buzzer without cutting the door for a wired device.
8) Should I use a deadlatch or a deadbolt on a commercial aluminum entry door?
A deadlatch like the 4913 is the traffic door choice. It is spring loaded, so the door relatches every time it closes, and the key controls hold back when you want the leaf to stay unlocked through business hours. A deadbolt secures better at night but has to be thrown deliberately every time, which is why storefronts run a deadlatch on the active leaf and a separate deadbolt or hookbolt where after hours security is the concern.
9) Is the Adams Rite 4913 rated for a high traffic commercial entrance?
Grade 1 and heavy duty, with a steel case and corrosion resistant plating. Grade 1 is the top ANSI/BHMA commercial tier, which is what a school, hospital, or municipal entry typically specifies. Solid brass latchbolt in a steel case is the combination that holds up on a door cycled all day.
10) Does the Adams Rite 4913 only work on aluminum doors, or can I use it on hollow metal and wood?
Aluminum narrow stile is what it was engineered around, but hollow metal and wood door options exist in the 4900 family. Either way the leaf has to be 1-3/4 inches and prepped for the 7/8 x 5-13/16 inch case at the backset you order.
11) The door already has BEST 6K Series hardware on it. Does the Adams Rite 4913 drop into that prep?
Do not assume it does. The BEST 6KL deadlocking latch belongs to the 6K Series and is prepped as part of that line. The Adams Rite 4913 is a 4900 Series lock body with its own case footprint of 7/8 inch x 5-13/16 inch, a 1-1/8 inch, 31/32 inch, or 1-1/2 inch backset depending on the version ordered, and a handing of LH or RHR versus RH or LHR. Verify the existing cutout against the 4913 case and backset before ordering; where the door is already routed for the 6K Series, staying in that series avoids a rework of the stile.
12) What finishes does the Adams Rite 4913 deadlatch come in?
US3 bright brass, US4 satin brass, US10B oil rubbed bronze, US32 bright stainless, and US32D satin stainless. On a storefront where only the faceplate shows, US32D is the usual match to anodized aluminum and stainless push pulls; pick the others when you are matching existing brass or bronze hardware across the rest of the building.
13) Do I need a flat or radius faceplate for the Adams Rite 4913?
That depends on the door edge you are working with. The 4913 installs with either a flat or a radius faceplate, matched to the edge configuration, and the bevel gets adjusted at install. Square edge aluminum stiles take the flat plate; a rounded or beveled edge takes the radius.
