Made in the USA. JPMA certified. Top and bottom of stairs certified. The wood slats are securely captured in the hardwood frame which is made of 100-percent American hardwood (poplar) and is unfinished to prevent allergic reactions in children and pets. It is "ready to finished" by the consumer using only children and pet approved finishes. The top and bottom frame rails are "beefy" to ensure strength and security. The wood stat design discourages "climbers". This gate is assembled using solid steel rivets and washers throughout to provide extra strength and prevent failures typical in gates assembled with screws. The gate easily mounts to opening using included hardware with simple hand tools. It features our soft touch latch for easy securing and a quick release mechanism so the gate can be completely removed when not needed. It is 31-1/2-inch tall, so it is ideal for taller children and larger pets. Recommended to be used in openings of 40-inch to 54.1-inch. 32-inch(h).
