    • Quality product, easy to install.
Style: NEW - 36-inch
Measured old threshold, this was a match on height and width. Cut old threshold in center with 5” metal cutting blade in grinder. Took out the 2 halves. Trimmed staples in jams with side cutters. Drove in new threshold with hammer and block of wood. Shimmed with wedges. Sealed with clear silicone to floor. Adjusted height with screwdriver. Works great. ... show more

    • Fits 36 inch exterior doors
Style: Discontinued - 36-inch
We just replaced all 3 of our exterior door thresholds with these from Frost King. They look great installed. They seem like they're sturdy and will last well. I like that the sturdy vinyl attaches to the metal. These replaced 30 year old hardwood and aluminum designed thresholds where the wood began to rot. Wood looks fancier, but I don't think the screws through exposed wood make a very water tight design. These have wood hidden under the vinyl, so the only exposed parts are water proof. It took some figuring for my husband to figure out how to separate the vinyl from the wood block, then snap them back together, but he got it done. We just finished off the installations with 100% silicone caulk around all the edges. ... show more

    • Worked as described
Style: NEW - 36-inch
This threshold was exactly what I needed to repair the gap under my door. It does require some trimming, so be prepared for that - it is not a custom made product. I also spend time applying a finish to the wood to protect it as it comes bare - finish to one's taste. It's a good product for the price and certainly got the job done. ... show more
