Lewmar Block Upstand Kit - 29904050

The Lewmar Block Upstand Kit is designed to hold a block to the deck in a vertical direction for sail control in recreational marine application only.

Features:

• Applications: 50 / 60 mm Control Blocks (singles and fiddles)
• Performance depends heavily on the specific application and suitability of installation
• Care must be taken during installation to ensure the block upstand is suitably aligned to the expected load
• The load direction should be as close to perpendicular with the base as possible, which will maximize the working load of the pad eye

Specifications:

• Safe Working Load: 990 lbs
• Weight: 0.8 lbs
• Base Diameter: 1 3/4"

Note: Under low load conditions some braided lines handle as if they are slightly larger than listed dimensions (ie XLS, Trophy, 3-strand and Brait). Use 72mm Synchro Series for loose weave 3/8" lines.
