Window Wedge - Cresci Products - 2 Pack

by Cresci

The Window Wedge with the Slip-Resistant Base, was designed and tested to act as an Adjustable Window Stop for double hung, single hung, and horizontal sliding windows. The Window Wedge is made of durable, impact resistant, ABS Plastic and has a tapered groove on the bottom that holds a strip of (Velcro® Brand) hook material that mates with an 8 inch strip of (Velcro® Brand) peel and stick loop material.

The loop material easily attaches to the window frame (See Directions) without the use of tools. The Window Wedge is then placed over the loop strip and pressed down at the desired window opening location.

NOTE: For Child Safety, maximum window opening should not exceed 4 inches. For a Quick Reference, the Window Wedge® package is 4 inches wide as shown in the Installation drawing.

Q: My child’s room has very low windows, would he be able to pull the wedge off the hook and loop strips?

A: It depends on your child’s age and strength. If your child is 17 years old or a mini Superman, then he/she might be able to pull it off.
