Corbin Russwin 863F038 – Frequently Asked Questions

1) What exactly comes in the Corbin Russwin 863F038 tailpiece pack?
It's a fixed core cylinder tailpiece pack for the CLX3300 Series cylindrical lever locksets, set up for Schlage and Sargent keyways. It's the tailpiece hardware only, not a cylinder and not a lock chassis. If your existing CLX3300 lever lock is fine and you're swapping in or re-fitting a fixed core cylinder, this is the connecting part between the cylinder and the lock chassis.
2) Will the 863F038 tailpiece pack work on a 1-3/8 inch door?
Yes. The 863F038 covers door thicknesses from 1-3/8 inch up to 2 inch, so it spans the thin older interior doors as well as the standard 1-3/4 inch commercial leaf and 2 inch doors. On the CLX3300 platform, 1-3/4 to 2 inch is the standard range and 1-3/8 inch is the D138 option, so if your lock was ordered D138 this tailpiece pack is the one that suits it.
3) I have Schlage keyed cylinders on my building. Can I use them with a Corbin Russwin CLX3300 lever lock?
That's exactly what this pack is for. The 863F038 is built to accommodate Schlage and Sargent keyways on the CLX3300 chassis, carrying the Schlage KIL designation. If your facility is keyed to a Schlage or Sargent system and you're putting CLX3300 lever locks on the doors, this tailpiece pack lets the fixed core cylinder from that system drive the lock rather than forcing you onto the Corbin Russwin standard L4 keyway.
4) Is this tailpiece for a fixed core or an interchangeable core cylinder?
Fixed core. The 863F038 is the fixed core version. The CLX3300 chassis itself is built to take all cylinder formats, from fixed core through interchangeable core, but the tailpiece is format specific, so an IC core cylinder needs its own tailpiece rather than this one. Check which core format is actually in the door before you order.
5) Does the door thickness adjustment on a CLX3300 lock affect which tailpiece I need?
It does, and that's why the 863F038 is specified by a thickness range rather than a single size. The CLX3300 uses a patented adjustable push/turn button to take up door thickness, but the tailpiece behind the cylinder still has to reach the chassis. This pack covers 1-3/8 inch through 2 inch doors. Anything over 2 inch, up to 2-1/4 inch, is the D214 territory on the lock and falls outside this pack's range.
6) Is the 863F038 a genuine Corbin Russwin part or an aftermarket piece?
Genuine factory component. It's the Corbin Russwin part made for the CLX3300 Series platform, model number 863F038. On a Grade 1 opening that matters more than usual, because the lock is certified as an assembly under ANSI/BHMA A156.2 (2022) Series 4000 and UL/cUL 3-hour, and substituting a non-factory internal part on a fire rated door is not something an AHJ will sign off on.
7) Will this tailpiece pack fit any Corbin Russwin lever lock, or only the CLX3300?
CLX3300 Series cylindrical lever locksets only. The 863F038 is engineered for that platform, and tailpiece length and drive geometry differ between lock families, so it should not be treated as a universal Corbin Russwin part. Confirm the chassis stamp reads CLX3300 before ordering.
8) Is this part suitable for high traffic commercial doors or just light duty?
Commercial duty. The CLX3300 platform it serves is ANSI/BHMA Grade 1 and UL cycle verified to 20 million cycles, with over 3,100 in-lb abusive locked lever torque and over 1,600 lbs offset lever pull. Typical placements are schools, healthcare, offices, retail, warehouses and multi-tenant residential, so the tailpiece is a maintenance part for openings that see constant use, not a residential fix.
9) Does handing matter when ordering the 863F038?
No. The CLX3300 lever lockset is non-handed, so there's no left or right version of the tailpiece pack to specify. You order the one part regardless of which way the door swings.
