How to Cut Vinyl Railing

Vinyl decks and siding are popular and economic choices when doing exterior remodeling. Vinyl has a longer lifespan than bare wood with less maintenance throughout the years. Vinyl is an option when choosing your exterior railings as well. Cutting your vinyl railing for installation is a fast and easy process once you know a few tricks of the trade. To cut this railing, you will need a bit of time, the proper tools and just a bit of know-how.

Straight Cut Level Railings

Cut Vinyl Railing
  1. Lay your vinyl railing onto the ground. Hook the blade of your tape measure onto the end of the handrail and pull it out just past the desired measurement. Place a dot with your marker on the side of the handrail 1/8 inch past your desired measurement.

  2. Place the miter box under the handrail at your mark. Hold the handrail tight against the miter box and adjust the rail so that your saw blade will hit the mark you made when it is in the 90 degree cutting position. Cut through the handrail with the saw.

  3. Measure and cut the bottom rail to the same measurement as the hand rail. Wipe away any vinyl debris from both rails.

Angle Cut Stair Railing

  1. Measure 1 inch from the end of the handrail and place a dot with your marker on the top edge of the handrail. Place the miter box under the handrail and align the mark with the cutting slot that will give you a 45 degree angle where the top of the rail will be the longest point. Hold the handrail and box firmly and make the cut with your saw. Repeat the procedure on the bottom rail.

  2. Measure the handrail along the top by hooking your tape measure onto the long end of the angle you just cut on the other end of the rail. Pull the tape along the length of the rail and place a mark 1/8 inch past your desired measurement.

  3. Place the miter box under the handrail at the slot for a 45 degree angle cut that will leave the bottom of the rail longer than the top. Hold the box and rail firmly and make the cut. Repeat the procedure with the same measurement and cutting angle on the bottom rail. Wipe away debris from both rails.
