# The collapsible ladder on my Alu-Cab roof tent won't lock in the lower rungs, is it defective?

This is normal for the Alu-Cab collapsible ladder design. All the extra rungs should be positioned at the top of the ladder so the weight rests on the ground rather than on the tent bracket. The rungs only lock into place when fully extended, so they won't lock when partially collapsed.
