REPLACES 8 INCHES OF ROTTED INSWING JAMB BOTTOMS

BOSS-RX REPAIR

  • Cutting and replacing jamb bottoms requires tools and competency in basic carpentry. Before ordering, verify with a tape measure the jamb width you need. We offer two sizes, so the width you need is either 4 9/16 in or 6 9/16 in. Next measure how much rot needs to be replaced on your jambs. BOSS-Rx Door Frame Rot Repair Kits replace up to 8 in. of rot on each of your jamb bottoms. Our added lap joints and 5 degree sill cuts simplify installation, provide greater strength, and are highly tolerant to adjustment if you don't manage to make a perfectly straight cut on your jambs. Solid PVC construction won't absorb water, rot, warp or split. Read the simple 4-step instructions in the Installation Guide on this page to understand the tools and skills you'll need to complete the job and help cut down on the carbon footprint caused by costly returns.

    ⭐️⭐️⭐️⭐️⭐️

    “This product is a lifesaver. I live in the Northeast and have doors that are exposed to a lot of moisture. This kit makes the job fast, easy, and permanent. Since it is made of PVC, I won’t have to do it again. You will need an oscillating tool to cut the old jamb and general/multi-purpose epoxy putty. I am planning on repairing another door with this kit. Excellent product, highly recommend.”

  • Good quality!

    ⭐️⭐️⭐️⭐️⭐️

    “Very good product! It fits perfectly. The youtube instructions made it very easy to install. I filled the gaps and painted it on top. It was like new! I only wish they offered longer option for door frame that is rotten more than 10”. I think that could be the only bad thing.”
