• Double Rubber Sealed and locking
• 40mm Internal Recess
• 58mm Overall Depth

• Solid tray base plate

For the external dimensions please add 80mm to the internal dimensions eg. 300 x 300mm Internal = 380 x 380mm External.

The 300 x 300mm has two lockdown screws whereas the others all have 4 screws.

Please note: It is a common error to measure the external dimensions of manhole covers.  The majority of manhole cover dimensions given by any supplier are the internal dimensions so please remember this when ordering.
