The product is very flimsy.  The hardware was awful.  The protective caps and washers (which were plastic) for the screws were broken inside of the packaging.   One of the J Bolts for the glider broke inside the blind nut.  What a nightmare.  My husband is a machinist and he created a metal bolt to make it work.  The trampoline was also a challenge to put together.  All I can say is good luck, signed: Very Disappointed.
