Truss mending plates are metal connectors used to join trusses and repair damaged ones. They are commonly made of galvanized steel, which makes them strong, durable, and resistant to rust and corrosion. In this post, we will discuss how to install truss mending plates effectively, step by step.

Safety Precautions

Before you start installing truss mending plates, make sure to take the necessary safety precautions. This includes wearing protective gear such as gloves, goggles, and a dust mask, especially if you are cutting or drilling wood. Also, make sure to work on a stable surface, such as a workbench, and use clamps to secure the truss to prevent it from moving.

Choose the Right Truss Mending Plate

The size and shape of the truss mending plate should match the size and application of the truss being joined or reinforced. Choose a plate that is at least as long as the damaged area or the length of the truss being joined. Make sure to choose a plate with enough holes to accommodate the nails or screws you plan to use.

Prepare the Truss

Before installing the truss mending plate, prepare the truss by removing any debris, dirt, or dust. Use a wire brush or sandpaper to clean the area around the damaged truss or the area where the truss mending plate will be attached. This will help ensure that the plate adheres properly to the wood.

Install the Truss Mending Plate

Here are the steps to install the truss mending plate:

  • Position the Truss Mending Plate: Place the truss mending plate over the damaged area or the area where you want to join two trusses. Make sure that the plate is centered over the damaged area and that the holes align with the wood.
  • Mark the Holes: Use a pencil or marker to mark the location of the holes in the wood. This will help ensure that the nails or screws are positioned correctly.
  • Drill Pilot Holes: Drill pilot holes in the indicated locations using a drill bit that is slightly smaller than the diameter of the nails or screws. As a result, the wood will be less likely to split, and it will be simpler to place the nails or screws.
  • Insert Nails or Screws: Insert nails or screws through the holes in the truss mending plate and into the pilot holes in the wood. Make sure to use enough nails or screws to ensure a secure connection.
  • Hammer or Screw the Nails or Screws: Hammer the nails or screw the screws into the wood until they are flush with the plate. Make sure that the plate is securely attached to the wood.

Inspect the Truss

After installing the truss mending plate, inspect the truss to make sure that it is securely attached and that there are no signs of damage or splitting. Test the truss by applying pressure to it or gently tapping it with a hammer. If the truss moves or makes a rattling sound, it may not be securely attached.

Finish Up

You can add a finish-up by removing any excess debris or dust and applying a protective coating or sealer to the wood to prevent further damage.

Installing truss mending plates is an effective way to repair damaged trusses and join two trusses together. By following these steps, you can ensure a secure and durable connection that will stand the test of time. Remember to take the necessary safety precautions and choose the right truss mending plate for your project to ensure a successful installation.
