The open bloc is an open handed bloc that you can about hang on to with an nice rounded juggy top that you can get both hands in, but has a nice taper over the rest of the hold, so you'll find it hard to stand on after you pass it.
it is 42cm x 30cm and comes out the wall by about 9cm
Made of hollow Dannomond
You can pick a colour, the option is above the price
This hold is screwed on (screws not included)
