Schaefer 1-3 Series Blocks

Schaefer

The Shaefer 1-3 Series Blocks are designed and developed with the same care and innovation given to their successful larger blocks. Constructed of tumbled and polished Stainless Steel. High impact Delrin sheaves turn on polished, stainless spacers to function with a minimum of friction, even under heavy loading. Head shackles are high quality Stainless Steel with clevin pin and cotter ring attachments.
