Abstract
In example implementations, a windlock is provided. The windlock includes a body, a windlock lip, and a gusset. The body includes holes to receive a fastener to be coupled to a slat of a roll-up door. The windlock lip is formed from a portion of the body that is bent from the body. The gusset is coupled to the body and the windlock to provide mechanical strength to the windlock lip.
Claims17
A windlock, comprising:
- a body, wherein the body includes holes to receive a fastener to be coupled to an end of a slat of a roll-up door;
- a windlock lip formed from a portion of the body that is bent from the body, wherein the windlock lip is inserted into a guide of the roll-up door to move within the guide and to secure the slat within the guide;
- and
- a gusset coupled to the body and the windlock lip to provide mechanical strength to the windlock lip, wherein the body, the windlock lip, and the gusset are formed from a single piece of 10 gauge steel.
