Kwikset KWI-971PSKSQT Single Cylinder Interior Pismo Knob Trim with Square Rose

The Pismo interior pack is trim only, so the exterior side is a separate purchase. You get the interior Pismo knob on a square rose plus the deadbolt turn piece and 2 keys; the matching Kwikset exterior pack has to be ordered on its own. Plan for both line items if you are building a complete opening.

No handing to specify. The Pismo interior pack is universal handing and fully reversible, so the same part goes on a right hand or left hand door. That is the reason it works as a fleet standard across a building where openings swing both ways.

It is built for Kwikset handlesets, specifically the Signature Series 814 and 818 handlesets. Pairing it with a different manufacturer's handleset is not something Kwikset states, so match it to a Kwikset Signature Series exterior and the two halves land on the same prep.

Single cylinder. The deadbolt throws and retracts from a thumb turn on the interior face, with the key working only from the outside. For a door with glass close to the lock, some jurisdictions push you toward a double cylinder instead, so check your local code before committing to a turn piece next to glazing.

It is certified ANSI/BHMA Grade AAA, the highest residential rating across security, durability, and finish. Grade AAA is a residential standard, not a commercial one, so for a Grade 1 or Grade 2 commercial opening this is not the right family of product.

Residential. Kwikset classifies the Pismo entrance trim as residential and grades it on the residential AAA scale. On an apartment unit door or a single family entry it is on spec; on a leasing office, storefront, or any opening carrying commercial traffic you want a heavy duty product instead. From the same category, the Codelocks CL510 and CL515 tubular latchbolt back-to-back and the CL610 and CL615 are listed heavy duty.

No - they solve different halves of the door. The Kwikset 971PSK Pismo interior pack is a knob trim with square rose and an interior turn piece that mounts to a Kwikset handleset, and the matching Kwikset exterior pack has to be bought separately for the opening to be complete. The BEST 8T-KL is a closet-function non-keyed tubular deadbolt with thumbturn, blank plate by thumbturn, sized for a 1-3/4 inch door - it is a standalone bolt with no outside operation and no keying at all. Use the 8T-KL where you want a thumbturn-only bolt on a bore of its own; use the 971PSK Pismo where a Kwikset handleset is already going on the door.

Move to a mechanical pushbutton lock. The Kwikset 971PSK Pismo interior pack is a keyed handleset trim - it ships with 2 keys and locks from an interior turn piece, so every entry is by key. If you want code entry instead, the Codelocks CL250 is a tubular latch with key override, and the Codelocks CL510/CL515 and CL610/CL615 are heavy duty tubular latchbolt back-to-back units in the CL500 and CL600 Series, meaning both sides carry a keypad rather than a keyed exterior. The tradeoff is style: the Pismo is a residential handleset trim in six finishes, while the Codelocks units are keypad hardware.

The Kwikset 971PSK Pismo interior pack is knob trim for a Kwikset handleset, which needs a stile deep enough for handleset boring - it is not narrow stile hardware. For a narrow stile door, the Lockey 2950 is a narrow stile hookbolt mechanical pushbutton lock with a 1-1/8 inch backset, and the Lockey 2500 Series is a mechanical keypad hook bolt lock with an adjustable backset; both cover doors from 1-1/8 to 2 inches thick. The hook bolt is the reason - it throws into a narrow jamb where a standard latch has nothing to catch.

Six finishes: Venetian Bronze, Satin Nickel, Bright Chrome, Satin Chrome, Satin Brass, and Matte Black. That covers the common residential palettes, so a property manager standardizing a building can usually match existing knobs and levers without changing finish families. Note the rose is square, so it reads differently against round rose trim already on the doors.

The Pismo interior pack is keyed and turn piece operated with no code entry, so it is the wrong product if you want codes. For mechanical pushbutton entry, the Lockey 2500 Series keypad hook bolt lock has an adjustable backset and fits 1-1/8 to 2 inch doors, and the Lockey 2950 is the narrow stile version with a 1-1/8 inch backset. If you want a code with a key override on a tubular latch, the Codelocks CL250 covers that.

It is. The Pismo pack bundles a knob, a square rose, and a keyed deadbolt for an entrance opening. For a plain thumbturn deadbolt with no key and no knob, the BEST 8T Series closet function tubular deadbolt is the simpler part: blank plate on one side, thumbturn on the other, sized for a 1-3/4 inch door.

The Kwikset 971PSK Pismo interior pack is residential hardware, certified ANSI/BHMA Grade AAA for residential security, durability and finish, and it is built to install in minutes with a screwdriver on a Kwikset handleset. For an opening cycling all day, the Codelocks CL510/CL515 in the CL500 Series and the CL610/CL615 in the CL600 Series are both rated Heavy Duty. Those are tubular latchbolt back-to-back locks, so they replace the whole lock rather than trimming out a handleset.

Yes. The Kwikset 971PSK Pismo interior pack is entrance-function hardware built to pair with a keyed Kwikset handleset exterior, which is more lock than an interior door usually needs. The BEST 8T-KL is a closet function non-keyed tubular deadbolt with thumbturn, blank plate by thumbturn on a 1-3/4 inch door - no cylinder, no keys, just a thumbturn on one face and a plain plate on the other. That suits a closet, storage room or utility door where you want the door held shut but never need to key it.

A screwdriver is all it takes. The interior pack mounts to the existing handleset prep in minutes, no drilling or specialty tools, which is why it is a practical unit turn item for a maintenance tech rather than a locksmith call.

The Pismo trim carries Microban antimicrobial product protection built into the finish, which Kwikset states keeps the hardware 99.9 percent cleaner than unprotected surfaces. It is a surface cleanliness claim on the hardware, not an infection control rating, so treat it as a touch point feature rather than something that satisfies a facility standard.
