Last reviewed: April 2026

Why this product
Beech Lane's interlocking blocks compete directly with Andersen Stax. Same concept — 10 HDPE blocks that lock together — at 40,000 lbs capacity. The 4.5-inch max height is slightly less than the Andersen 5-inch, but enough for most sites. At 6 lbs total for 10 blocks, they pack light.
