I bought this to attach my mont blanc vista 450 roof box to my breeze block garage wall. Very easy to assemble. I used No.12 x 2" screws (6.0 x 50mm) and Fischer High Performance Plug (SX 8X40) wall plugs (holes drilled using an 8mm masonry drill bit) and it went up a treat - so much more space in my garage now!
I bought this to help train for Tough Mudder. I had looked at a door frame bar but they seem to mark the wall and door frame and I wanted something I could leave in place rather than being sat in the back of a cupboard most of the time. Very simple assembly. Despite being pretty inept at all things DIY and only having use of a cordless drill I managed to install this on my breeze block garage wall without any trouble. It feels very sturdy to use - no creaking or bending. The bar is a good distance from the wall. All in all, I'm very pleased with this product.
