2 Installation Procedures 

Step 1

, Install mounting hardware

A)  

For glulam installations, attach the glulam brackets to the beam using ½” through bolts, 

not supplied.  Note, ½” lag screws, also not supplied, may be used as an alternative, but 

will not provide as much mounting strength.  Be sure the brackets line up with each other 

and that the bottom of each bracket is flush with the bottom of the beam.  For glulam 

installations, attach the mount directly to the bracket using the supplied ½” x 2 ¾” bolts, 

washers, and nylon lock nuts.  

B) For 

steel I-Beam installations, mount so that the large plate is against the bottom of the 

beam.  Be sure the plate is at a 90 degree angle to the beam and centered.  Place the 

supplied clamps on top of the beam and attach them to the mount using the supplied 

fasteners.  For thicker I-beams, use the supplied shims between the clamp and the mount 

as shown in figure 3. 

Note: In all cases, be sure to thoroughly tighten all mounting bolts and nuts.  The nylon lock nuts 

help prevent loosening due to vibration, but there is no substitute for proper tightening.  We 

recommend that nylon lock nuts not be removed and reused because this will defeat the 

nylon locking; instead, buy new nylon lock nuts from your local hardware store. 

C) 

If an extension is to be used, attach it to the bottom of the universal mount using the 

fasteners provided with the extension.  Also, be sure to save the longer safety cable and 

guy wire supplied with the extension; they will be needed in a later step. 

D) 

Loop supplied safety cable (1/4 inch steel braided cable) over the beam and let it hang.  

It will be attached once the power unit is installed.  If using an extension, be sure to use 

the longer safety cable supplied with the extension.
