The original Rock design was developed 19 years ago by Mark Valance and has been refined over the intervening years to create the definitive piece of passive crack protection.

The unique shape is engineered to take up the most stable position in any crack, the convex side locking against the two 'feet' of the concave side, creating a stable triangulation of forces. Planar side tapers ensure stable side placements and allow you to 'turn-key' rocks into pockets. The over-barrelled edges and corners together with the use of carefully selected 6064 T6 aluminium extrusions ensure rocks 'bed' into the crack but can be 'cleaned' easily.
