As you know, the velcro straps that hold the rain covers in place on days where we do not have rain have aged to the point of not working. We found some commercial grade snaps which we hope will solve the issue. Fairly easy to work and they do seem to hold fast in place. I've attached a video which demonstrates how the snaps should be used. The strap must be pulled from the front to the back or it will not come off. We will get all carts completed by early next week. Eight carts were changed today.
