MULTICRAB - TECHNICAL INFORMATION - 2023 124 TECHNICAL DATA COMPONENT LOAD RATINGS 0.15 m ledger If you want to double a standard to halve compressive force, fix a tube and two couplers at the junction. Underneath, the 0.15 m ledger maintains the spacing between two standards and helps with assembly. The 0.15 m ledger facilitates assembly but the load is ensured by the tube and coupler stiffener. Shearing force PROHIBITED F F/2 F/2 2-bolt junction couplers and CRAB couplers are used for interconnecting with low load take-up (connections between towers, guardrails). For high load take-up, use 4-bolt couplers.
