Kwikset KWI-971HFLSQF Single Cylinder Interior Halifax Lever Trim with Square Full Escutcheon

Interior side only. The 971HFL Halifax lever trim with square full escutcheon is the inside half of a handleset, and the Kwikset exterior pack has to be ordered separately. If you're replacing just a worn or damaged interior lever and escutcheon and keeping the exterior handle on the door, this is the piece you want. If you're doing a full opening from scratch, budget for both halves.

It's built for Kwikset handlesets, specifically the Signature Series 814 and 818 handlesets. Kwikset interior packs are matched to the handleset family, so pairing the Halifax square trim with a handleset outside that pairing is not something to assume.

No handing to specify. The Halifax lever is fully reversible and installs on either a right hand or left hand door, so one part number covers both swings. For a property manager buying several at once for a building, that means you order quantity, not handing.

No. The Halifax interior lever is non-functioning, it doesn't operate the latch. Locking is done with the turn piece on the inside of the lock, and the exterior handleset carries the operating function. Buyers expecting a working inside lever on a passage or entry set should be aware of this before installing.

No, they occupy different bores and do different jobs. The Kwikset 971HFL Halifax is interior lever trim with a square full escutcheon, with a non-functioning lever and a turn piece on the interior face, and it is sold as an interior pack that needs a matching Kwikset exterior pack to make a complete handleset. The BEST 8T-KL is a closet function non-keyed tubular deadbolt with a blank plate on one side and a thumbturn on the other, sized for a 1-3/4 inch door. The BEST unit throws a bolt on its own; the Halifax trim carries the lever and turn piece for a handleset already in the door. Fitting one where the other was specified leaves the opening either without a latch or without a handle.

The 971HFL Halifax is mechanical trim with no code capability - the lever is non-functioning and the only operation on the interior side is a turn piece. For keypad entry, the Lockey 2500 Series is a mechanical keypad hook bolt lock with an adjustable backset that fits doors 1-1/8 to 2 inches thick, and the Codelocks CL250 from the CL200 Series is a tubular latch with key override, so an authorized holder can get in with a key when the code is not being used. Both are complete locks in their own right rather than trim, so switching to one changes the door prep and removes the need for a separate exterior handleset pack.

The Halifax 971HFL is classed as residential hardware, built as interior handleset trim for a home entry door. For an opening that takes commercial traffic, the Codelocks CL510 and CL515 in the CL500 Series and the CL610 and CL615 in the CL600 Series are both tubular latchbolt back-to-back locks rated heavy duty. Those are self-contained locks with operation on both faces, so they replace the handleset entirely rather than dressing one side of it, and the door will need the prep their series calls for.

No. The 971HFL Halifax carries a square full escutcheon, a long plate that needs stile width a narrow aluminum door does not give you, and it is residential handleset trim that depends on a matching Kwikset exterior pack. For a narrow stile opening, the Lockey 2950 is a narrow stile hookbolt mechanical pushbutton lock built on a 1-1/8 inch backset for doors 1-1/8 to 2 inches thick - the hookbolt suits a sliding or narrow frame condition where a standard latch has little to grab.

It's a residential product. The Halifax lever trim is rated for residential use and is sold as part of Kwikset's Signature Series, so it suits single family homes, apartments, and light multi-family entries. For a commercial opening where a Grade rated tubular lock or deadbolt is called for, look at commercial lines instead, such as the BEST 8T Series tubular deadbolt with thumbturn, which is specified for 1-3/4 inch doors.

The Halifax interior pack is trim for a keyed Kwikset handleset, so it won't give you code entry. For keypad access on a rental or a shared door, the Codelocks CL250 tubular latch offers a key override alongside the code, and the heavy duty Codelocks CL510/CL515 and CL610/CL615 back-to-back tubular latchbolt models are built for higher traffic openings. For a gate or a narrow stile door, the Lockey 2500 Series hook bolt keypad lock fits doors from 1-1/8 to 2 inches thick.

They are two separate Codelocks families of the same configuration. The CL510 and CL515 belong to the CL500 Series and the CL610 and CL615 belong to the CL600 Series, and all four are tubular latchbolt back-to-back locks carrying a heavy duty rating. The series designation is what identifies which family a replacement or a keyed-alike addition has to come from, so order to the series already on the other doors rather than to the configuration alone.

A screwdriver. That's it, the interior pack goes on in minutes with no drilling or specialty tools, which is why it's a practical swap for a maintenance tech doing several doors in a day rather than a job that needs a locksmith.

Yes, it carries Microban antimicrobial product protection, which Kwikset states keeps the hardware 99.9 percent cleaner than unprotected surfaces. That's a touch surface benefit on high traffic doors in hospitality or assisted living, though the product itself is a residential grade item.

It's the shape of the full escutcheon plate behind the lever. The 971HFL SQF is the square version, giving straight edges and corners to match contemporary handleset styling. Function is identical either way, the escutcheon shape is purely how the trim looks against the door, so pick the one that matches the exterior handleset and the other openings in the house.
