Model selection at a glance
SDX-400RLB
8–40 mm bar / 24–47 mm coupler OD
SDX-400RL
16–40 mm bar / 24–60 mm coupler OD
SDX-6ET / SDX-10ET
Pipe platform: 16–53 / 20–63 mm clamping range, not a rebar connection capacity.
SDX-15ET / SDX-20ET
Pipe platform: 40–80 / 75–115 mm clamping range. Identify the contact surface and working access.
Compare both bar and coupler dimensions
For a 32 mm bar with a 40 mm coupler outside diameter, SDX-200RLB falls outside its 19–31 mm coupler range. SDX-400RLB and SDX-400RL include both dimensions in their listed ranges. This creates a dimensional shortlist; the connection-system requirements and access still need checking.
Power and working position distinguish the shortlist
SDX-400RLB lists battery / power line, while SDX-400RL lists power line. SDX-400RL also lists horizontal rebar, column rebar, steel couplers and reinforcing cages among its supported connection configurations.
Keep installation requirements explicit
The published maximum tool torque is not an installation setting. Use the connection-system requirements and obtain project-specific technical confirmation.
Plan the handover
Record the approved connection procedure, inspection responsibilities and required tool configuration before ordering. This selection guide is not an installation manual.
