Homeowner

This is a very good quality replacement sill. My only comment is that the adjusting screws are not exactly equally spaced. I cut exactly 3/4" off each end and the end screws are about 1/4" different in position to the end. It looks like it will work but be careful when you cut this sill to length.

Good product, may require some work

Shipped promptly and arrived intact. Requires a bit of hand work around fasteners as holes are not clean. Some splintering around edges which is fussy to sand out as fasteners are fixed. Be aware fasteners are 1/4-20 so it may not be exact match for original which used larger fasteners. I had to cut length offset and precisely drill and tap new holes in aluminum threshold. It absolutely did what I needed though.

Double Door Sill

When we moved into our home we found that the sill plate on the double doors was in pieces. I did not want to replace the entire threshold. I purchased this product at I received it overnight, even without expedited shipping. It was very well packed and after removing 1/2 of an inch with a hacksaw, it fit perfectly! Couldn’t find this item anywhere else.

Pricy, but works

Pricy for what it is, but worked fine. Had to shim the bottom for my application. Would be really nice if a height dimension was provided in the dimensions drawing or description.

Worked perfectly

This shipped super fast from when I ordered it. It was easy to install because of the video they provide. Once installed, the door shut even better. I didn’t realize the sill nosing cap was separate but was able to epoxy that part back together before installing this piece.
