Adams Rite 4511-15-101-628 – Frequently Asked Questions

1) Will the Adams Rite 4511 deadlatch fit my narrow stile aluminum storefront door?
The 4511 is built for narrow stile aluminum doors, and the deciding number is backset. It comes in 7/8, 31/32, 1-1/8, and 1-1/2 inch backsets, so you measure from the stile edge to the cylinder centerline on your door and order the matching one. Door thickness is 1-3/4 inches. The latch body itself is 1 x 5-13/16 inches by depth, so your mortise pocket has to take that. Hollow metal and wood door versions exist as well.
2) What backset do I order on an Adams Rite 4511 and how do I measure it?
Four backsets are offered: 7/8, 31/32, 1-1/8, and 1-1/2 inch. Measure from the edge of the stile to the center of the cylinder hole on the door you are replacing. Getting this wrong is the most common ordering mistake on narrow stile deadlatches, because the faceplate will still sit flat while the cylinder lands off the stile centerline. Handing is a separate choice, LH or RHR versus RH or LHR.
3) Does the Adams Rite 4511 deadlatch come with a cylinder?
No cylinder is included. The 4511 takes any standard 1 inch length mortise cylinder with the Adams Rite MS cam, ordered separately. If you are keying a building to one system, that is the piece you match, not the latch, so the same 4511 works across keyways as long as the cylinder is a 1 inch mortise cylinder with the MS cam.
4) Will the 4511 latch into the strike that is already in my jamb?
Throw is the thing to check. The 4511 latchbolt throws 1/2 inch, with latch dimensions of 1/2 x 1 x 1/2 inch, so it needs a strike keep cut for a shallow bolt, not a deep deadbolt pocket. The standard strike for the 4511 is the 4902-01, for a flat jamb where the door closes flush. If your existing keep is deeper or shaped for a different bolt, order a strike with the latch rather than trying to reuse it.
5) Which strike do I pick for a center hung aluminum door versus a standard jamb?
Strike shape follows the jamb and the stile. Choices are Flat/Standard Jamb, Radius/Standard Stile, Flat/Center Hung 4 inch Jamb, and Flat/Center Hung 4-1/2 inch Jamb. Center hung doors need one of the two center hung versions, sized to whether your jamb is 4 or 4-1/2 inches. Strike size is separate: 2-5/8 inch mortised or 4-5/8 inch mortised, matched to the cutout in the jamb.
6) Is the 4511 deadlatch handed, and what happens if I order the wrong hand?
Handing matters. Two options are sold, LH or RHR and RH or LHR, and each covers a left hand door plus its reverse bevel opposite. Order the wrong one and the latchbolt bevel faces away from the strike, so the door will not latch on close. Stand outside the door: if the hinges are on your left it is right hand or left hand reverse, hinges on the right is left hand or right hand reverse.
7) What do I need to order besides the deadlatch to finish the job?
Three things beyond the 4511 body. Mounting screws come with it, and so does the strike you select. You supply the mortise cylinder, 1 inch length with the Adams Rite MS cam, plus whatever outside trim or pull the door needs. If the opening is going on access control, the electric strike replaces the standard 4902-01 keep.
8) How does the Adams Rite 4511 deadlatch compare with the BEST 6KL deadlocking latch?
They are built for different door types. The Adams Rite 4511 is a standard duty deadlatch with a 1/2 inch throw and a 1/2 inch x 1 inch x 1/2 inch latchbolt, carries a Grade 1 rating, mounts in a 1-3/4 inch thick door, and takes a mortise cylinder that is not included. It is engineered for narrow stile aluminum doors and comes in backsets of 7/8 inch, 31/32 inch, 1-1/8 inch and 1-1/2 inch to suit the stile you are working with. The BEST 6KL is a Grade 2 deadlocking latch with steel construction from the 6K Series. If your opening is a narrow stile aluminum entrance and the hardware schedule calls for Grade 1, the 4511 is the one that matches on both counts.
9) Can a BEST 6KL latch be used in place of an Adams Rite 4511 on an aluminum storefront door?
Treat them as separate hardware families rather than drop-in alternates. The BEST 6KL is a Grade 2 deadlocking latch in the 6K Series. The Adams Rite 4511 is specifically engineered for narrow stile aluminum doors, accepts standard Adams Rite MS cam mortise cylinders, and pairs with the 4902-01 strike for a flat jamb where the door closes flush. Swapping in a latch from a different family means the cylinder cam, the mortise pocket and the strike prep all have to be re-verified against the door you already have. For a storefront stile already cut for a 4510 Series deadlatch, the 4511 keeps that prep intact.
10) Can I hold the latch back so the door stays unlocked during business hours?
Yes, that is the point of the 4511. It has a bolt holdback function, so you retract the spring loaded latchbolt and hold it back to leave the door on free entry during open hours, then release it after close. That is why these show up in retail, healthcare, and multi tenant lobbies where the door has to behave differently before and after hours.
11) Do the Adams Rite 4511 finishes match the anodized aluminum doors already in my building?
Three anodized finishes are offered on the 4511: 628 clear anodized, 313 dark bronze anodized, and 335 black anodized. Those are the three standard storefront aluminum colors, so for a property manager standardizing a run of entrances the faceplate will read the same as the door frames rather than sitting on them as a bright plated part.
12) Is the Adams Rite 4511 rated for heavy commercial traffic or should I step up?
The 4511 is a Grade 1 commercial deadlatch, but it is the standard duty model in the 4510 Series. All metal construction with hardened steel internal pins. For a normal storefront entrance or a tenant suite door it is the right level; for an opening cycling constantly all day, look at a heavy duty deadlatch in the same family instead of specifying this one and replacing it early.
13) Can I put the 4511 deadlatch on an access control system with a buzzer entry?
Yes. The 4511 works with Adams Rite electric strikes, so the usual setup is the latch in the door and an electric strike in the jamb wired to a card reader or a lobby buzzer. The latch itself stays mechanical, which means a key override in the mortise cylinder still works if the strike loses power.
14) What is the difference between the Adams Rite 4511 and the BEST 6KL deadlatch?
Different openings. The 4511 is a Grade 1 narrow stile deadlatch cut for aluminum storefront, with backsets down to 7/8 inch and a 1 x 5-13/16 inch body. The BEST 6KL Series is a Grade 2 deadlocking latch with steel construction. If you are working an aluminum entrance with a narrow stile, the 4511 backset range is what makes it fit; the 6KL is the pick when you are in a BEST 6K Series keying system.
15) Our facility standard calls for Grade 1 latching hardware. Which of these deadlatches meets it?
The Adams Rite 4511 is rated Grade 1 and is a commercial product with a 1/2 inch throw latchbolt. The BEST 6KL is a Grade 2 deadlocking latch. If the specification on the drawing reads Grade 1, the 4511 is the one that answers it, and it can be standardized across an aluminum entrance program in dark bronze anodized, black anodized or clear anodized to match the existing openings.
