## Overview

The Defender Security S 4751 Fixed Window Guard is a robust, non-egress safety barrier made from 0.048-inch thick carbon steel tubing with a sleek black finish. It features a telescoping width adjustable from 31 to 54 inches and tamper-proof one-way screws for secure installation. Designed to prevent accidental child falls, it complies with NYC, NJ, and Oregon safety codes but is not suitable for bedrooms without alternate emergency exits.

## Description

This window guard is constructed of 0.048 inch thick, plain carbon steel square tubing and comes in a black painted finish. Note: This is a fixed window guard, meaning that once it has been installed it cannot be opened nor easily removed in the event of an emergency where entry or exit through the window would be required. For this reason, THIS FIXED WINDOW GUARD SHOULD NOT BE USED IN BEDROOMS OR SLEEPING QUARTERS WHERE NO OTHER EMERGENCY EXIT WINDOW IS ACCESSIBLE. For windows requiring emergency access capabilities, please use appropriate hinged version of these window guards, like Prime-Line part S 4779. This child fall window guard is non-operational and it is designed for interior use only. The intended purpose of this guard is to assist in preventing children from accidental falls through open windows. This window guard features a fully adjustable telescoping width (prior to mounting), and it comes complete with one-way, tamper-proof installation screws. This child fall window guard meets New York City and New Jersey’s housing codes, and it was approved by the New York City Department of Health and Mental Hygiene, HDWG #04-09-2010, but it does not meet egress.

Review: A great grille which extends and looks good. Does not wobble and appears to be very strong. Just be careful if you do decide to use the non-returnable screws supplies because you will literally never be able to remove the grille. You'll likely have to cut it off the fixings if you ever want to remove it.
Review: Pretty good sturdy
