Precast concrete Kelly blocks and Lego blocks for counterweights, stooling, temporary retaining walls and site delineation, made to tier 1 quality with full lifting certification.

Modcast Kelly blocks are solid precast concrete blocks made in our North Wangaratta factory for counterweights, stooling, temporary retaining walls and site delineation. Every block is cast with Swift Lift style lifting anchors, so it can be handled safely by crane from the yard to its final position.
Our blocks are manufactured to tier 1 quality requirements. Each unit can be supplied with lifter certification and a birth certificate, giving you the traceability major projects expect for anything that is lifted or relied on as a counterweight.
| Block | L × W × H | Mass |
|---|---|---|
