Cuplock Cantilever Extension Adapter
Engineered to international standards for safety, speed and durability on every job site.
Overview
The Cuplock Cantilever Extension Adapter - also called a cuplock cantilever bracket or cuplock extension adapter - is a forged steel fitting that drops into a cuplock cup node on a standard and carries a cantilever arm so a working platform or ledger can project horizontally beyond the standard. It seats with a forged blade that drops into the bottom cup and locks with the top cup, turning any cup node into a cantilever support point. Offered as the CEA model at 2 kgs in hot-dip galvanized steel, it is built to OSHA, ANSI and CSA guidelines with a 4:1 safety factor, ISO 9001 quality and FOB Shanghai delivery from ACE SCAFFOLD.

Key Features
- Hot-dip galvanized Q235/Q345 carbon steel
- Seats at any cuplock cup node - forged blade into bottom cup, top cup locks it
- Carries a cantilever arm to project a platform past the standard
- Standard model CEA, 2 kgs unit weight
- Reaches over walls, columns, machines or edges without a standard
- Built to OSHA, ANSI and CSA guidelines, 4:1 safety factor, ISO 9001, FOB Shanghai
On a cuplock scaffold, the cuplock cantilever extension adapter is the way to push a working platform or line of ledgers past the last standard without setting a standard out there. The adapter seats on a cuplock standard at any cup node: a forged blade drops into the welded bottom cup and the forged top cup is tapped down to lock it with a single hammer blow, so the fitting is held rigidly on the standard while the rest of the node stays free for ledgers and braces. From that node the adapter carries a cantilever arm or spigot that reaches out beyond the standard, so a platform, walkway or row of transoms can be projected over a wall, column, machine or edge where a standard cannot stand. Because the adapter uses the cuplock cup node rather than a loose clamp, nothing projects into the climbing space and the bay keeps its standard geometry. Our cuplock cantilever extension adapters are hot-dip galvanized Q235/Q345 carbon steel, built to OSHA, ANSI and CSA guidelines with a 4:1 safety factor, ISO 9001 quality and FOB Shanghai delivery from ACE SCAFFOLD.
Cuplock Cantilever Extension Adapter
The cuplock cantilever extension adapter is a forged steel fitting that drops into a cuplock cup node on a standard and carries a cantilever arm so a working platform or ledger can project horizontally beyond the standard.
Cup-Node Seating
The adapter seats on a cuplock standard at any cup node. A forged blade drops into the welded bottom cup and the forged top cup is tapped down to lock it with a single hammer blow, so the fitting is held rigidly while the rest of the node stays free for ledgers and braces.
Cantilever Reach
From the node the adapter carries a cantilever arm or spigot that reaches beyond the standard, so a platform, walkway or row of transoms can be projected over a wall, column, machine or edge where a standard cannot stand.
Hot-dip Galvanized
Every cuplock cantilever extension adapter is hot-dip galvanized Q235/Q345 carbon steel for corrosion resistance on site, coastal and offshore projects, and is built to OSHA, ANSI and CSA guidelines with a 4:1 safety factor.
