Ledger Connection Example STEP 1:

Choose a floor joist inside the house that is adjacent to where the deck is supported. The location should be free of obstacles (air ducts, pipes, wires) and fairly easily accessed.

Hold a bracket in place and mark the location for the hole to be drilled through the band board and the ledger board. Remove the bracket and drill a 1/2 " hole through the ledger and the band board. (See photos 1.1 & 1.2.)

STEP 2:

From the inside of the house, install a 1/2" x 5" bolt in the bracket and push the bolt through the hole that was just drilled.

From the outside of the house (under the deck) install a flat washer, lock washer and retaining nut on the bolt. Thread the nut on loosely to allow adjustment of the bracket. See photo 2.0

STEP 3:

Back inside, hold the bracket tight against the floor joist and drill through one of the four holes in the bracket to allow for a bolt to be run through the floor joist.

NOTE: KEEP THE DRILL AS LEVEL AND SQUARE AS POSSIBLE WHILE DRILLING THESE HOLES!

STEP 4:

Install a 1/2" x 3" bolt in the new hole and place a second bracket on opposite side of floor joist. Slide the bracket over the protruding bolt through the corresponding hole. Install a flat washer, lock washer and retaining nut onto the bolt. Hand tighten the nut to hold the second bracket in place. See photo See photo 4.0

STEP 5:

Drill a hole in the band board and ledger board through the second bracket and install a 1/2" x 5" bolt.

STEP 6:

Drill a second hole through the floor joist and have your drill bit go through corresponding, holes in both brackets. Install 1/2" x 2 1/2" bolt. Install flat washer, lock washer and retaining nut and tighten with socket or wrench.

STEP 7:

From the outside, install flat washer, lock washer and retaining nut on the second bolt.
