The Cardinal Gates Stairway Special Outdoor Safety Gate (Model SS-30-ODC) is the maximum safety gate for children. As its name indicates, this gate is designed for top-of-stairway or bottom-of-stairway use but is great for decks, patios and other outdoor areas. It features a latch that allows one-handed operation. The gate can swing open in either direction. A stop bracket (optional to use but included) prevents the gate from opening out over the stairs, for greater safety. The Stairway Special Outdoor Safety Gate will mount at angles up to 30° allowing location of a stud when mounting on drywall. Temporary removal of the Stairway Special Safety Gate is fast and easy, without having to unscrew the wall-mounted hardware. The gate is constructed of aluminum which is lighter weight than steel. Included stainless-steel hardware makes this the best gate on the market for outdoor use. A powder-coated finish provides a long lasting, easy-to-clean surface. Two different size width extensions are available: 10.5 in. and 21.75 in., each sold separately. The Stairway Special Outdoor Safety Gate is available in white, black or brown. Material: Metal.
