NOTE:

Lay the lumber on a flat surface

before beginning laminated beam assembly.

NOTE:

Attach one end of the beam with three

2-1/2'' screws. Secure boards and attach the

other end with three 2-1/2'' screws. This will

insure that your boards will stay aligned

throughout the remainder of the beam assembly.

K. Laminated Beam Instructions

1. If 4" x 6" lumber is not available, you may

laminate two 2" x 6" x 144'' pieces of lumber

together to create the beam.

2. Lay the lumber on a flat surface and align all of

the edges. NOTE: Make sure each piece of

lumber is the same length. If it is not, trim board(s).

3. From the end of each board, measure and place a

mark at 24" intervals (Fig. 18).

4. Assemble the beam by attaching each end

together using three 2-1/2'' screws (Fig. 18a).

Note: Stagger the screws as shown in (Fig. 18a)

to insure a sturdy bond. Repeat every 24" along

the entire length of the beam.When beam is

complete, measure, drill holes, and attach beam

clamps and nylon bushing swing hangers

Optional Laminated Beam
