Retaining Cups

The Econ-O-Cap Steel Retainer is designed to securely hold compression pads and fit over the ends of concrete cylinders, forming a reliable unbonded capping system for compression testing.

Machined from high alloy steel to the same tolerances as testing machine platens, these steel retainers provide accurate, consistent load distribution without deformation under load.

• Precision-machined high alloy steel construction
• No deflection under load for consistent test results
• Minimal temperature variation for reliable performance
• Scratch-resistant surface, eliminating the need for re-machining
• Forms part of a safe, clean, and economical unbonded capping system
• Eliminates noxious odors and burn hazards associated with traditional capping methods

Available sizes:

• 2", 3", 4", and 6" diameters
