LEWMAR 29901362BKClick To Copy 30mm Control Block, Thru-Deck Double

Ball bearing blocks deliver sensitivity to hand held loads. This 30mm thru-deck double block is ideal for getting control lines out of the way. Commonly used on dinghies thru-deck blocks run control lines below deck or under cockpit seats so that you can position them in easy to reach areas. The additional sheave of the double allows two separate control lines to be run to one centralized location; ideal for travelers. The smaller sheaves are compatible with up to 5/16" Sailors can detect changes in wind intensity and direction by feel. Hand held loads of the main and headsail, spinnaker and other control lines communicate valuable information to the crew. Lewmar Control Blocks are designed to keep these lines of communication open. By using ball bearings, Control Blocks assure sailors that small signals won t be lost in unnecessary drag or friction. These light weight blocks are ideal for control lines and other hand-held loads. Long fiber technology used in the construction of the composite cheeks adds strength while keeping the overall weight down. An open design is used in the cheeks to reduce maintenance: saltwater and sand can be easily flushed from the block and the bearings lubricated. The sheaves use the same long fiber technology for strength and feature a metal insert for the bearing surface. This addition improves performance and longevity. Line size compatibility and safe working loads are indicated on the sheave of each block to avoid failures caused by overloading the block.
