For sites that have neglected to specify a restriction device, it is not too late to rectify. The Wrekin reducer ring can be retrofitted to standard 450mm diameter clear opening Wrekin manhole cover frames, allowing customers to be confident that they can make their scheme compliant in future if they happen to overlook installation of these safety accessories when the cover is first put in place.
Straight forward to install, the reducer ring can be bolted into place for peace of mind. Additionally, we can factory fit this accessory to avoid confusion on site and ensure compliance from the start of your project.
