This self-closing gate with midrail meets OSHA, ANSI and Canadian COHS load requirements twice over, helping you protect workers using ladders to get to elevated work or storage areas. A unique spring design prevents slamming and allows you to adjust the speed of the self-closing function. This model covers widths from 20" to 30", which makes selecting the right model easier and allows you to cover a range of openings with just one model number.
