Child Safety Window Guard by Guardian Angel REGULAR (23"-35"W) - $69.95
A must for multi-level homes. The safest window guard on the market! Others are permanently mounted, which could spell disaster in a fire. This one withstands 150 lbs. of pressure, yet removes easily with emergency release buttons. The steel bars are closer together than others (3 7/8 " apart; not 4-5".) The only brand recommended by the city of Boston. Works with single and double-hung windows, as well as sliding and hinged casement windows (does not work with crank-out windows.) Side posts screw mount into your window frame - it's very easy. Please measure your window widths (frame to frame) before ordering.
