Let-In Brace

A let-in brace is a way of bracing studs around a window, or other places where cut off studs are used. The let-in brace is comprised of four boards placed in a large diamond pattern around a window. "Let-in" means that the studs are cut to make way for the braces.

  • Step 1: Measure out how long you need your let-in brace to be and cut it to size. Don't forget to cut the ends at angles.
  • Step 2: Lay the boards onto your framing project over top of where they will be going. Use a marker to trace the outline of the boards onto the studs.
  • Step 3: Remove the board and set your saw to cut 1" down. Cut out the sections and insert the let-in brace. You may have to go back and trim some areas if the brace doesn't fit at first.
  • Step 4: Nail the let-in brace firmly to the other studs.

Let-In Brace, Cut-In Brace, and Diagonal-Sheathing Brace

There are three types of stud braces, and a let-in brace is just one of them. Cut-in bracing cuts the braces up into small pieces and places them diagonally between each stud. Diagonal-sheathing uses 5/8 inch plywood to cover the entire frame diagonally.
