THIS LISTING IS FOR A NEW HARKEN 4 1/2", 112MM DOUBLE BIG BOAT FOOT BLOCK FOR MAX 5/8" LINE. PREDECESSOR TO THE CURRENT BLACK MAGIC BLOCKS, WITH BOTH BALL BEARINGS AND ROLLER BEARINGS, VERY STRONG BLOCK, HAS AN 8,050 LB SAFE WORK LOAD. SEE PHOTOS FOR COMPLETE SPECS. 

I AM STARTING OFF WITH 2 OF THESE, PHOTOS SHOWING BOTH ARE TO SHOW THAT THEY ARE IN SIMILAR CONDITION, BUT THE LISTING IS FOR A QTY OF ONE WITH 2 AVAILABLE. AT THE TIME THIS WAS LISTED I ALSO HAVE 2 NEW SINGLE 4 1/2" SINGLE STAND UP BLOCKS LISTED. 

I AM HAPPY TO COMBINE SHIPPING INTO THE LEAST EXPENSIVE FLAT RATE CONTAINER FOR MULTIPLE ITEMS, EITHER A PADDED FLAT RATE ENVELOPE, OR A SMALL, MEDIUM, OR LARGE FLAT RATE BOX AND WHATEVER FITS CAN SHIP TOGETHER FOR THE COST OF ONE FLAT RATE CONTAINER.
