The CCL 13mm Enclosed Spring-Loaded Grip (SLA-Type) is a precision-engineered anchor designed for active prestressing applications using 13mm diameter 7-wire strand. The enclosed housing, internal spring and capped body provide rapid installation, reliable strand retention and consistent load transfer under stressing.

 

This grip is available in two options:

  • Grip-Only – enclosed body with cap, spring and O-ring (no wedge)

  • Complete Assembly – grip body pre-assembled and pre-lubricated with wedge, spring, cap and O-ring

 

The enclosed design is commonly used at the non-stressing end of prestressing beds, where quick fitting and secure wedge retention are essential. The internal spring ensures the strand remains positively engaged, even when jacks do not feature power lock-off or when detensioning multi-strand beds.

 

Enclosed grips help to minimise pull-in losses and speed up bed preparation. Because they contain several internal components, they require slightly more careful cleaning and handling than open-type grips, but provide highly dependable performance in everyday precast operations.

 

Key Features

  • Fully enclosed spring-loaded anchor body

  • Available as Grip-Only (no wedge) or Complete Pre-Lubricated Assembly

  • Designed for 13mm 7-wire prestressing strand

  • Fast installation with reduced risk of wedge seating pull in losses

Strand Compatibility 

The 13mm enclosed grip uses wedge 604204, which is compatible with the following strand sizes:

 

European Seven-Wire Strand (EN 10138)

  • 12.50mm (1770 MPa / Breaking Load / UTS = 173 kN)

  • 12.90mm (1770 MPa / Breaking Load / UTS = 186 kN)

  • 12.70mm (1860 MPa / Breaking Load / UTS = 186 kN)

  • 12.90mm (1860 MPa / Breaking Load / UTS = 190 kN) 

  • 13.00mm (1860 MPa / Breaking Load / UTS = 208 kN) 

 

American Seven-Wire Strand (ASTM A416 Grade 1860)

  • 0.500in (12.70mm) / Breaking Load / UTS = 183.7 kN 

 

(Note: Customers using non-standard strand should contact CCL for confirmation of compatibility.)

 

Usage Notes

  • Ensure strand is cut square and free of deformation

  • For complete assemblies, no lubrication or assembly is required – ready to use immediately

  • Inspect internal components regularly in high-cycle environments

  • Avoid impact damage to the cap or press-in tube during handling
