Our deck organizer blocks are a significant upgrade compared to the standard equipment used on boats built after 1986. They have several advantages over competing blocks as well.
Stainless steel frame is robust and looks good longer than competitors' aluminum and plastic frame blocks
Two 1/4" bolts mean fewer holes in the deck than the typical four 3/16" bolt pattern with similar strength
Anodized aluminum sheaves won't self destruct in the sun like plastic sheaves
2-1/8" hole spacing is the same as original Catalina supplied deck organizer blocks so you don't have to drill new holes
Large 2" diameter sheaves with ball bearings turn freely with minimum friction
Frame size 5-1/8" long by 1-3/4" wide
Suitable for Halyards and control lines on boats from 22 to 30 feet
