Retention Socket

Retention sockets are ideal solutions when it comes to replacing posts that are damaged by vehicle collide. With the help of pole retention sockets, the originally difficult and dangerous post-changing and reinstalling work gets easier.

Skyhall Fence has taken international standards and post-foundation requirements into consideration and developed various retention sockets to meet the rigorous demands of current urban environments.

In addition to complying with various regulations, we are also concerned about the safety of construction workers, drivers, and pedestrians. With the help of retention sockets, congestion on the road network is significantly reduced by eliminating repeat excavation.

Feature & Benefits

Durable and Reusable

The high-strength retention sockets are durable enough to survive vehicle impact. And due to the re-usability, retention post sockets provide cost-effective solutions for infrastructure maintenance and post replacements.

Make Project Easier

By traditional methods, traffic signal posts and signposts are installed in concrete or bolted to a concrete foundation. Complex procedures are needed especially when it comes to post changing or reinstalling. On the contrast, the retention sockets will eliminate repeat excavations and make your project completed easier and faster.

Friendly to Environment

By eliminating repeat excavations, retention sockets significantly reduce the damage to the environment that might be caused previously.
