PAVA - Built-in extension capabilities
The PAVA 10, 14 and 19 surface boxes are surface boxes with built-in extension capabilities.
The lower base of the body features screw-nut type threads and is designed to allow the unit to be raised during road resurfacing operations by simply « unscrewing » the assembly.
Delivered with the body built-up of 30 mm, they can, in the event of roadway repair work, be retracted or evaded during the surfacing milling, so avoiding the damage so much in the machines and in them same.
Easy levelling is planned from the origin installation.

PAVA 10 and 14 - Use of the PAVA lid by reversal for extension operation
Studied to facilitate the extension, the PAVA surface box lid once returned, it serves as tool to manoeuvre the body of the surface box which is generally taken in the surfacing. Equipped with two studs forming an operating nut, the inside face of the lid can be used to adjust the extension height using a plain 30 mm wrench or with a Tee wrench used for valve operation.
PAVA 19- Use of a specific operating lid
