The Cardinal Gates pinch guard (2-pack) helps protect your little one's fingers from door slamming accidents. Strong yet flexible, the non-toxic plastic is more durable than similar products made of foam which can be crushed. Easy to use, simply slide the U shaped pinch guard onto the door out of a child's reach. May be installed on hinge, latch side, or top of door. Only one needed per door. Designed for indoor use only.
