Components:
A - 1/2 “-13 Grade 5 Bolts
(at least 2-1/2” longer than the beam
is wide) (4)
B - 1/2” Flat Washers (8)
C - 1/2” Nylon Locking Nuts (4)
D - Glulam
This method is recommended for Glulams or wood beams 5-1/8” or wider. For narrower
attachment points please refer to the Unistrut mounting method to span across two or more
beams to increase the structural integrity.
1.3.1B:
Place a Glulam bracket against the beam and use a level or straight edge to line the
bottom of the bracket up against the bottom of the beam. Trace the locations of four bolt holes
and the two long sides of the Glulam bracket on the Glulam or wood beam.
1.3.2B:
Once marked, flip the Glulam bracket over so the long side is against the bottom of the
beam and line the short side up with the markings you previously made. Now mark the sides of
the Glulam bracket along the bottom of the beam.
1.3.3B:
Flip the Glulam bracket over to the other side of the beam and line the bottom of the
bracket up with the marking along the bottom of the beam. Now mark the same four bolt hole
locations and remove the bracket. Using a 1/2” wood bit drill out the four bolt holes from both
sides.
1.3.4B:
Install both brackets with the recommended hardware and hand tighten so the brackets
are left loose.
