The Model 12 Universal Block is the solution to your search for a quality engineered sheave that is lightweight (9.4 lbs.), versatile, durable, and dependable. It can be intermixed with  similar stringing blocks and mounting attachments manufactured by others, without affecting conductor sag or tension.

The quality of the model 12 block is not surpassed by any block of its type. Its aluminum parts are cast from high strength A356 alloy, heat treated to the T6 condition, giving it the capability of withstanding rough treatment under adverse conditions while supporting heavy loads.

The Model 12 may be attached directly to ANSI 52-3 & 5 ball and socket insulators using the socket eye supplied as an integral part of the unit.

The gate latch is designed for safe, smooth, single motion hot stick or hand operation. The latch gate can be locked in the open position, leaving the lineman’s hand free for conductor removal from the sheave groove. When the latch is released, the gate closes and locks automatically nothing to twist, turn, or push.

The sheave groove is profile machined for concentricity, thus permitting more precise sagging of the conductor. In addition, the block is available with urethane sheave lining (Model 12-UL). The Model 12 has adapter mounting lugs on each side of the frame. These allow positioning the sheave horizontally, if desired, when used with the many attachments available for the block.
