In the absence of a
standardized test in the gutter industry that could be used to
evaluate the pull value of hangers, Raytec developed the test
procedure demonstrated below. |
The
procedure consists of a set of gripper hooks attached to the outside
edge of .032 Aluminum gutter. Standard hidden hangers were screwed
into a 3/4" fascia board backed by 2" x 4" spruce, with a 1 1/2" hex
head screw. A screw jack was used to pull the gripper hooks at an
angle of 45% with an "S" type load cell measuring the lbs. of force
exerted on the hanger. Displayed on a Totalcomp electronic digital
indicator, each hanger was evaluated for the amount of sag it
displayed at various weights and, finally, the point at which it
broke.
Our tests are in
no way intended for use other than comparing one hanger with another.
Twelve hangers of similar mounting
configuration, commonly used in the gutter industry, were evaluated.
The Raytec Hangtite™ proved superior to all of
the hangers tested. Of the total tested, the Raytec hanger is priced
at about the mean average of the group.
Findings:
- At 119 lbs. pull, 4 of our competitors'
hangers broke loose.
- At 140 lbs. pull, 3 more of our competitors'
hangers broke loose.
- At 230 lbs. pull, 4 more of our competitors'
hangers broke loose.
The Raytec Hangtite™
hidden hanger hold up to 297 lbs!
