DR16 Mechanical Anchor

Mechanical anchors, often called headed bars, are secured to the end of a length of reinforcing steel bar (rebar), creating anchorage within the concrete. This approach greatly simplifies reinforcing bar placement and reduces congestion. Headed bars are often used as a replacement for hooked bars.

The nVent LENTON Ultimate Mechanical Anchors are designed for high performance applications. The Ultimate Mechanical Anchors are permanently installed at the fabricator and will not loosen or fall off during transportation or installation.

Typical applications for Ultimate Mechanical Anchors include beam to column, roof to column, piles to caisson, and future extensions. Ultimate Mechanical Anchors are ideal for all forms of construction including dams, subways, bridges, high rise buildings, water treatment plants and stadiums.
