Accentra 50-1178-0003-048 – Frequently Asked Questions

1) Will the Accentra 1178L swivel spindle work on a 1-3/4 inch door?
Yes. The 1178L swivel mortise spindle covers door thicknesses from 1-1/4 inch up to 1-3/4 inch, so a standard 1-3/4 inch commercial door is within range, as are thinner 1-3/8 inch interior doors.
2) What size spindle is the Accentra 1178L, and will it fit my lever hubs?
It is a 3/8 inch spindle, the standard square size for mortise lever hubs, so it mates with lever trim cut for a 3/8 inch spindle. If your existing trim uses a knob spindle or a different hub size, this is not the part.
3) Is the 1178L spindle for a lever-by-lever mortise lock or a lever-by-knob setup?
Lever by lever. The 1178L is built for lever x lever Yale mortise lock configurations, so both sides of the door need lever trim. A knob on one side calls for a different spindle.
4) Does the 1178L spindle fit Yale 8800 series mortise locks?
Yes. It is made for Yale mortise locks and is directly compatible with the 8800 series, which makes it the swivel spindle to order when rebuilding or re-trimming an 8800 mortise lock.
5) What exactly am I buying with the Accentra 1178L, the whole lock or just a part?
Just the spindle. The 1178L is a swivel mortise spindle, a lock trim component that transfers lever rotation into the mortise case. It does not include levers, roses, escutcheons, cylinder, or the mortise case itself, so those come from the lock and trim you are working with.
6) What does the swivel design on this mortise spindle actually do for me?
The swivel lets each lever turn independently through the spindle instead of forcing both sides to rotate as one rigid bar. On lever x lever mortise trim that means smoother lever throw and less wear over a long service life, which is why it is specified in high-traffic commercial openings.
7) What part number do I give my supplier for the Accentra 1178L spindle?
Order it as Accentra 1178L, model number 50-1178-0001-048. One spindle covers the full 1-1/4 to 1-3/4 inch thickness range, so there is no separate length to pick for standard doors.
8) I'm standardizing mortise hardware across a multi-family property. Can one spindle cover doors of different thicknesses?
For doors between 1-1/4 and 1-3/4 inches, yes, the 1178L handles the whole range, so you can stock one spindle for mixed unit and corridor doors as long as the locks are Yale mortise, 8800 series included, and the trim is lever on both sides.
9) Is this spindle rated for high-traffic commercial doors, or is it a residential part?
Commercial. The 1178L is classified as commercial door hardware and is used in office buildings, schools, healthcare facilities, retail, industrial buildings, government buildings, and multi-family residential corridors, anywhere the mortise levers get cycled hard.
