Pendock CH Plywood Casing Systems

CH enclosures are primarily designed for covering and protecting larger diameter pipework, including heating services, soil and vent pipework, rainwater pipes, heat recovery ducting, etc. which are located in mid-wall applications, vertically or horizontally.

Enclosures are supplied either as pre-finished components fitted with assembly joints to facilitate site installation or, where appropriate, as single units.

The enclosures are available to individual size requirements, based on a pair of angle casings (MX range) with an additional flat front section and/ or additional flat side sections. A range of factory-assembled joints are available (J8, J2, J3, J4 and J5).

All profiles are 90° angles, with radiused corners. Internal radius is 21.5 mm.
