Kindorf®
• Traditional Trapeze Installation Methods
– Most common way to attach strut to threaded rod is with hex nuts and
square washer. (Photo 1).
– Rarely is a strut nut used for this application (cannot adjust the trapeze
height once installed because strut nut cannot be turned). (Photo 2).
– Some will use 2 flat washers and 2 hex nuts to sandwich the bottom of
the strut (cheapest materials, harder to adjust). (Photo 3)

Trapnut™ Strut Fastener
Caddy Smart Nut
Provides a hex nut type attachment which can
be installed in line with the rod. To use this part,
a square or flat washer still needs to be inserted,
unlike the Trapnut which integrates all of these
components. Additionally it has a relatively light
load rating (200 lbs) compared to 3/8” threaded
rod (600 lbs) or the Trapnut (590 lbs).

Trapnut™ Strut Fastener
Slip On® Lock Nut
Hex nut type attachment which can be installed in
line with the rod. Like the Caddy Smart Nut, to use
this part, a square or flat washer still needs to be
inserted. Additionally, due to the nature of the
machining used to manufacture this part, it is
significantly more expensive than the Trapnut.
B-Line® Hot Rods™
Short length of threaded rod pre-assembled with strut nut, square washer
and jam nut. This product is undesirable because it employs a strut nut
which doesn’t allow for adjustment once installed.
