The Light Source Mega-Gridlock Half Black, Punch, Stamp

All Spacer Plates for Track Hangers & Gridlocks can be supported from the 1/2" outside holes with chain or threaded rod. Only the 5.732 Double Spacer Place and the Triple Spacer Plate have hole spacing for a Mega-Gridlock to fasten on the top center. The Double Spacer Plate does not have the correct spacing for a gridlock on the top. Both the Double and Triple Plates have 6" centers as well as center holes for a Mega-Coupler or a Mega-Claw.
