The Lewmar Block Upstand Kit 29904050 is a marine accessory designed to hold a block in a vertical position on deck. It is intended for sail control in recreational marine applications.

The kit has a safe working load of 990 lbs when properly aligned and installed. Key specifications include a base diameter of 1 3/4" and a weight of 0.8 lbs.
