Rigging Blocks for Arborists & Climbers

Rigging blocks help climbers create mechanical advantages that reduce the weight of loads and make the rigor of tree work easier for professional arborists and climbers.

Tree blocks are especially important in rigging applications with ground crews lowering heavy limbs. Pulley blocks help a single person lift double their typical strength with the same amount of force, which becomes insurmountably beneficial during a long day of limb removals.

Bartlett’s Block-Sling combos take all the guesswork out of which rigging line to pair with which block! We have pulley blocks for all rope diameters, including our popular seller Block-Sling Combo for ½” Rope.
