Klein Tools 1802-30 Block and Tackle

They are four end configurations of the same 25-foot rig. The 1802-30 comes with the Cat. No. 258 anchor hook, the 1802-30S with the Cat. No. 268 block, the 1802-30SR is spliced to the Cat. No. 268 block, and the 1802-30SSR is spliced to the 259 anchor hook. Klein's convention is that catalog numbers followed by S/R have the rope spliced to the block, so if you want a factory splice rather than a field-tied termination, order one of the SR or SSR versions.

The hooks are shaped to fit under the insulator and engage the pin on the cross arm, so the rig hangs off existing pole hardware without extra slings. The galvanized-steel shell blocks also carry snubbing hooks, which let you hold the load in place without tying off separately.

25 feet of 3/8 inch (9.53 mm) diameter nylon rope. All Klein block and tackle use the same 3/8 inch rope diameter, so the 25-foot length is the figure that decides reach: it is the total rope in the rig, not the lift height, and a multi-sheave reeving divides it down.

The shell blocks are galvanized steel and the rope is nylon, both of which hold up to outdoor exposure. Sheaves are aluminum alloy running on all-bronze bushings, so the moving parts are corrosion tolerant and lighter to carry up a pole than a steel-sheave block.
