Single right-angle coupler for fixing putlogs or transoms to a standard without rotation.
The putlog coupler is a single jaw fitting that clamps one tube to another at right angles but with only one bolted connection, so it does not rotate about the standard. It is widely used for fastening putlogs, transoms and toe-board supports where only one tube needs to be gripped.
One forged jaw holds the transom or putlog rigidly at 90° to the standard, preventing rotation under load.
With only one bolt to tighten, erection is quicker and material weight per node is lower.
The jaw is die-forged from carbon steel so it resists deformation on repeated use.
Suits putlogs, transoms, toe-board bearers and small ledgers in tube-and-coupler systems.
Available hot-dip galvanized or painted to match your fleet specification.
Dimensions follow EN 74 / BS 1139 series. Custom sizes produced to drawing.
