Accentra 50-1178-0001-048 – Frequently Asked Questions

1) Which size Accentra 1178L swivel spindle do I need for my door?
The 1178L swivel spindle is offered in two lengths, 1-3/4 inch and 2-1/4 inch. Measure the door thickness at the lock prep and match it: a standard 1-3/4 inch commercial door takes the 1-3/4 inch spindle, and thicker doors or applications with heavy trim rosettes take the 2-1/4 inch. Ordering the short spindle on a thick door leaves the lever hub without enough engagement.
2) Will the Accentra 1178L spindle work on a knob x knob or lever x knob mortise lock?
No. The 1178L is built for lever by lever mortise lock assemblies. Knob trim and mixed knob/lever configurations use different hub and spindle arrangements, so this part is the wrong choice there.
3) I have Corbin Russwin mortise locks, not Accentra. Can I use this spindle?
Use the spindle made for the lock you have. For Corbin Russwin mortise cases, ZenSupply carries the Corbin Russwin Swivel Spindle Pin X Set Screw, listed for 1-3/4 inch doors. The Accentra 1178L is dimensioned for Accentra lever x lever mortise assemblies and should not be cross-fitted.
4) What is the Corbin Russwin alternative to the Accentra 1178L swivel spindle for a mortise lock rebuild?
Corbin Russwin offers a Swivel Spindle Pin x Set Screw assembly listed for 1-3/4 inch door thickness. The Accentra 1178L swivel spindle is built for lever x lever Accentra mortise lock assemblies and is offered in 1-3/4 inch and 2-1/4 inch sizes, so a 1-3/4 inch opening can be served either way, while a 2-1/4 inch door is covered by the Accentra 2-1/4 inch size. Note the Corbin Russwin part is a pin and set screw style assembly, so match it to a Corbin Russwin lock body rather than dropping it into an Accentra case.
5) What does a swivel spindle actually do in a mortise lock?
It is the bar that ties the two levers together through the lock case so turning one retracts the latch. The swivel design lets each lever operate independently where the function calls for it, rather than both levers moving as one rigid unit. When levers feel loose, spin without retracting the latch, or only work from one side, the spindle is the usual culprit.
6) Is this a genuine Accentra part or an aftermarket spindle?
It is an Accentra factory replacement part, model 50-1178-0001-048, from the manufacturer's lock parts and accessories program. That matters on a mortise case, where hub tolerances are tight and a generic spindle can bind or wear the hub.
7) Is a swivel spindle pin and set screw kit the same thing as the Accentra 1178L spindle?
They serve the same function - carrying lever motion through the mortise case - but they are not the same part. The Corbin Russwin item is a Swivel Spindle Pin x Set Screw assembly, while the Accentra 1178L is the swivel spindle itself for lever x lever Accentra mortise lock assemblies, sized to door thickness at 1-3/4 inch or 2-1/4 inch. For an Accentra mortise lock being restored to original operation, the 1178L is the matching replacement part.
8) Is the 1178L spindle rated for high-traffic commercial openings, or is it residential grade?
Commercial. It is specified for commercial door hardware service, which is what you want on school corridors, healthcare units, offices and multi-tenant buildings where the lever sees constant use.
9) Do I have to pull the mortise lock out of the door to replace the spindle?
The spindle passes through the lock case hub, so both levers and their roses come off and the case has to be loosened or removed to free the old spindle and seat the new one. Plan on the lock coming out of the pocket rather than a trim-only swap. The 1178L is sold as a spindle only, so reuse your existing levers, roses and set screws.
