PRODUCT TEST DATA

Results of Load Testing our Concealed and Extended Concealed Brackets
with 9”, 12”, 18” & 24” Extender Arms

two shelves in a garage supported with concealed brackets

All sizes of our concealed and extended concealed brackets were load tested using the following method: the brackets were tested for ultimate load by being mounted to a post fixture and load applied in center of the horizontal arm of the bracket. This simulated the actual mounting of the bracket on the wall.

The brackets were then each mounted in the fixture prepared for use with the Riehle Universal Testing Machine. Each of the specimens was subjected to load until 1400 lbf was reached, and thereafter, load was increased until the arm yielded, i.e., the point of reaching the ultimate load. The results for all 4 sizes tested from the 9” Extender Arm to the 24” Extender Arm Brackets ranged from 1800 – Ultimate Load to (lbf)/Pair to 7960 – Ultimate Load (lbf)/Pair.
