The LOCKEY GL2LINX178 is a mounting adapter designed to install the SUMO GL2 gate closer on chain link gates with a 1-7/8 inch frame rail diameter. The adapter provides a secure, stable interface between the GL2 closer and the round tubular top rail common to residential and light commercial chain link fencing. Licensed gate hardware installers and fencing contractors use this adapter to complete a proper GL2 installation where standard mounting brackets are not compatible with chain link construction. At 3.45 pounds and compact dimensions, the unit is easy to transport and handle on-site.
This adapter is intended for use with chain link gate frames that feature a 1-7/8 inch top rail. It is suited for residential fence gates, commercial property access points, and light industrial perimeter gates where the SUMO GL2 hydraulic closer is being installed. The adapter is sold individually and is used as a direct component in the GL2 closer installation process. It is not a standalone closer and must be used in conjunction with the compatible GL2 unit.
Designed for use with the LOCKEY SUMO GL2 gate closer on chain link gate frames with a 1-7/8 inch top rail diameter.
Installation is typically performed by a licensed fencing contractor or gate hardware professional. Before mounting, confirm the gate rail diameter matches the 1-7/8 inch specification to ensure a secure fit. Follow the SUMO GL2 closer manufacturer instructions for proper adapter positioning and fastener engagement. Verify the gate structure is stable and properly plumbed before attaching the closer assembly.
