Used the 24” slides to install a 52 qt ice cooler on its long axis in the hatch of a teardrop trailer. At first, the slide would only lock in the closed position and the half-open position, but not in the fully open position. The seller advised to “pull the drawer slide a few times hard”. It worked, and now opens fully and locks only in full open and full closed position. Very strong…I stood on the platform fully extended and felt completely secure. I won’t downgrade because of mounting hardware, because I knew I’d need something specific anyway.
