Function: this handle locks by pushing the lock button in, so you do not need a key to lock it.
Fits: the sliding door on most Utilimaster, Supreme, Union City, Grumman, and Morgan-Olson bodies 1986-
To lock, just push the button in. To unlock, use the key. Here's a tip: use your deadbolt too for total security.
This is the 5/16" shaft. This part has been discontinued for current era step vans, all shafts now are 3/8".
Stats: Polished chrome finish; brass mechanism. 5/16"" x 3 3/4" shaft. Measure this by removing your door handle and using a 3/8" drive socket, insert it's shaft into the ratchet end of the socket, not the nut end. If the shaft fits snugly, it is 3/8". If it is loose, it is 5/16". Mounting holes are 4 7/8" top to bottom, and 1 15/16" center to center.
Note: Use with inside latches our Part# DS4000 (traditional slim handle). Special Note: if you have a Grumman Olson body, this is not the exact replacement for the original handle with the double sided key, but it will fit as a replacement. The double sided key is available only from Grumman (now Morgan-Olson) and it is on the expensive side.
Installation Note: the shaft on the new handle connecting the outside handle and inside latch might (probably will) be longer than your current handle. This is no accident - Kason leaves it long so the handle will fit a variety of bodies and model years; no two body builders and bodies are exactly alike. Just cut the shaft off to match what you have now. * Please keep and re-use your current mounting bolts, they are not included.
