Actual conditions of use usually result in bearing capacity below laboratory conditions.3. These brackets are easy to fold and self-lock for added security. They feature a spring actuated "forced latch" that can be locked in the open position to ensure stability. When not using a desk or workbench, simply press the latch and fold down for more space.4.
