Abstract: A stop assembly for a sliding closure includes a wedge-shape stop member which may be removably secured to the closure in a position where the stop member will become wedged between the relatively sliding members to preclude opening more than a predetermined distance. Cooperating pad-like elements having respectively numerous hooks and loops thereon are affixed to the closure and stop member, respectively, and when in mating engagement resist separation in a direction parallel to the direction of movement of the sliding member to preclude opening of the closure and are readily separable in a direction normal to such direction of movement to remove the stop member to permit unobstructed opening of the closure. When not in use, the stop member may be independently secured in a convenient storage location where it will not interfere with such closure movement by another pad-like element cooperating with the element affixed to the stop member.
