#40 Roller Chain Master Link – Connecting Link
#40 Roller Chain Master Link – Connecting Link
This #40 master link connects the ends of a compatible #40 roller chain. Use it when assembling a new chain loop or reconnecting a chain during garage door operator or chain hoist service.
PRODUCT DETAILS
• Part type: Roller chain master link, also called a connecting link
• Chain size: #40
• Matching #40 chain pitch: 1/2 inch
• Quantity: One master link
COMPATIBILITY
Use with #40 roller chain that matches the link’s dimensions and fastening style. Check the size stamped on the existing chain or consult the equipment manual before ordering. A matching pitch alone does not establish a proper fit; verify the chain size and link construction.
INSTALLATION & SAFETY
Disconnect power and secure the door before working on the chain drive. Connect the chain ends and install the link’s retaining components according to the applicable equipment instructions. Check that the connection is secure, the chain is aligned and correctly tensioned, and all guards are back in place before operating the door.
