Question: Do these racks swivel flush with wall when not in use??
Document: Great value, easy to install. I had 2 kayaks on the wall within 20 minutes - and they kayaks stayed there ready for me to take them out
Working out great thus far. They are bigger than I thought is my only issue given where I have them mounted (tight garage area) but I would recommend them.
This works like magic! We had to hang two kayaks and these did the trick. I would highly recommend these.
This is a great product for the money. Installation was easy. Centerline holes make fastening to studs easy. Strong hooks.
It works really well. We just had to get a set longer screws to make it work, but other than that, well worth the money
Great product, It met all of my needs and was very easy to install. The hooked shape of the product was plenty big to handle various size kayaks and was also very well padded as to not cause any damage either.
Answer: no
