DESCRIPTION
The UCAN drop-in anchor is an internally threaded anchor which is preassembled with an internal expansion plug. These fire resistant anchors
are available in both carbon steel and stainless steel. The carbon steel
anchor is zinc plated to extend corrosion protection.The stepped installation tool allows for correct anchor setting. The anchor is designed to
deliver consistent holding power at shallow embedment.
