Designed for interior installation, this fixed window guard helps reduce the risk of accidental falls while adding an extra layer of protection against unauthorized access. The non-egress design remains permanently secured and does not open, making it suitable for applications where emergency escape access is not required. Constructed from durable .048 thick plain carbon steel square tubing, this security grate is built for long-lasting residential use. The adjustable telescoping design expands from 23-1/2 in. to 38 in. wide before installation, allowing it to fit a variety of window openings. Featuring 3-7/8 in. on-center bar spacing, the grate balances safety and visibility while maintaining a low-profile appearance. Installation is secure with the included one-way tamper-resistant screws, helping prevent unauthorized removal. This window guard meets ASTM F2090 testing requirements and is designed to comply with applicable New York City, New Jersey, and Oregon building code requirements. Verify window dimensions and local code requirements before purchasing and installation. From the Manufacturer This window guard is constructed of .048 thick, plain carbon steel square tubing and comes in a white painted finish. Note: This is a β€œfixed window guard,” meaning that once it’s 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 OR DOOR IS ACCESSIBLE. For windows requiring emergency access capabilities, please use appropriate hinged version of these window guards, like Prime-Line’s model number 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.
