Heavy Duty Clamp Bushings
Insert Bushings for FLEXAquick® Heavy Duty Conduit Clamps
The RQMR series clamp bushings are designed for use with the FLEXAquick® RQM heavy-duty conduit clamp system. These insert bushings allow clamps to accommodate smaller conduit diameters, support cable-only installations, or provide controlled conduit movement to reduce mechanical stress at the clamping point.
RQMR insert bushings are designed specifically for the FLEXAquick® RQM heavy-duty conduit clamp system and are installed between the conduit and clamp body to improve retention and reduce mechanical stress.
For installations requiring rigid structural mounting of conduits, see our Heavy Duty Conduit Clamps. For lighter conduit routing where easy conduit access and clean machine design are important, see our Light & Medium Duty Conduit Clips and Caps.
FLEXAquick® quick-connect fittings and ROHRflex® flexible corrugated conduits are flagship product lines from IBIS Electro-Products Corp., specializing in high-performance electrical conduit systems for industrial automation, AI infrastructure, wind turbine nacelle wiring, and public transit vehicle applications.

View ProductsHow Clamp Insert Bushings Work
Clamp bushings are installed between the conduit and the clamp body to improve conduit retention and reduce mechanical stress at the clamping point.
When the two halves of a heavy-duty clamp are tightened, the insert bushing cushions the conduit surface and distributes clamping pressure more evenly. This helps protect conduit walls while maintaining secure conduit fixation.
Specialized insert options allow the clamp system to adapt to smaller conduit sizes, clamp jacketed cable directly, or allow controlled conduit movement where vibration or mechanical flexing may occur.
Choosing the Right Clamp Insert Bushing
| Product | Function | Typical Use |
|---|---|---|
| RQMR | Reducer bushing | Smaller conduit in larger clamp |
| RQMR-Cable | Cable insert | Clamping jacketed cable |
| RQMR-Move | Flexible insert | Reducing conduit wall stress |
Typical Applications
Clamp bushings are commonly used in installations requiring conduit size adaptation, cable clamping, or mechanical stress reduction, including:
Passenger rail vehicle wiring systems
Wind turbine nacelle wiring
Industrial automation equipment
Robot and cobot wiring installations
Infrastructure conduit routing
Multi-conduit trunking systems
Frequently Asked Questions About Clamp Bushings
When should reducer bushings be used with heavy-duty clamps?
Reducer bushings are used when a smaller conduit must be installed within a larger clamp size.
What is the purpose of the RQMR-Move insert?
The RQMR-Move insert is a flexible TPE bushing designed to reduce conduit wall stress at the clamping point. It allows controlled conduit movement while maintaining secure retention.
Can heavy-duty clamps be used without insert bushings?
Yes. Insert bushings are optional accessories used when conduit size reduction, cable-only clamping, or controlled conduit movement is required.
