TrueHolds Mantel block (affectionately known as the Big Boy). This is a combination mantel block and sloper (depending on orientation). Great for heel and toe hooks, blocking holds, compression moves and much more. We wanted to make a comp style hold that is still light enough and small enough to go on a home wall. It's suitable for all angles of the wall but becomes tricky on overhangs greater than 30°. Due to our holds being made to order, please allow up to 10 days for dispatch.
