Great replacement!

Had to replace my old one and this fit perfectly. Shipping was pretty good. Took 4 days to get it.

Exactly what I needed; by far the best price; came quickly and well-packed

I am a homeowner who needed to replace a Marks lockset for my front door. UHS offered exactly the set that I needed (in both left-hand and right-hand orientation), had it in stock, and was much less expensive than anyone else offering the lockset. The order was processed and shipped quickly and arrived well-packed with all the parts I needed. The installation proceeded perfectly, and I now have a shiny, secure new lock and knob on my front door.
