Vallast Roller Chain Half Link, #2040

Vallast Roller Chain Half Link, #2040

A precision roller chain half link designed for #2040 chain systems, the OLA2040E Vallast Half Link allows quick chain length adjustments without removing a full link. Built from durable carbon steel, this offset link helps achieve proper chain tension and alignment in mechanical and agricultural drive systems. It’s a small but important component—because a chain that’s just a little too long or too short tends to remind you the hard way.
