Schaefer 3 Series Block
Schaefer is currently shut down and we are not expecting any shipments from Schaefer until at least the end of April. Items which are not in stock at Defender may experience an extended lead time until they re-open.
Schaefer 3 Series Blocks are perfect for small cruisers, daysailers and high performance racing dinghies. The quality metal construction can take the punishment associated with running rigging mounted on the deck or to spars.
- Front or side shackle mounting prevents the block from swiveling/twisting
- Tough hardcoat anodized aluminum cheeks
- UV protected Delrin sheave
- Schaefer blocks withstand the elements and potential mishaps far longer than other brands with standard plastic cheeks and sheaves
