The 42″ Boulder will make up the majority of most walls. The primary characteristics of the Full Boulder are its 48″ front face tapering back to a 32″ rear face, with two parallel channels on the top surface and two interlocking box lugs on the bottom surface.

The tapered block is a benefit when building curved walls as it allows the turning of a radius in shorter distances and with no cutting. If your radius is extremely tight, simply knock off the necessary box lugs and rely on the ball lug to keep the two units interlocked.

*Limestone face texture was used when calculating weights.  All unit weights are +/- 5% depending place of manufacture and style of block.
