For attachment in uncracked concrete

Technical Details UPAT UKA3

The UKA3 shear connector is ideal for anchorage in uncracked concrete on account of ist very good price-performance ratio.

This shear connector has been successfully used for many decades. However, it does not meet with the requirements for use in cracked concrete.
