All covers and frames manufactured to BS EN 124-2:2015. Multi-part units are dimensioned to the pit
clear opening; manhole clear openings are typically 20mm greater on each axis. Tolerances +15mm /
−0.0mm. Beams supplied hot dip galvanised. Other sizes made to order — contact our Telford
sales team.

Commonly specified for data centres

Three sizes in this range are among the most often specified on data centre projects, for chilled water valve chambers, cable draw pits and plant pits in service yards: 1800 x 1800 (MPD180180), 2000 x 2000 (MPD2020) and 3000 x 3000 (MPD3030). Where covers need to be lockable and tamper resistant, see our data centre access covers.

Larger openings

Multi-part units are not limited to the sizes listed. Length is extended by adding support beams and rows of covers, and we supply units over 30,000 mm long and up to 3900 mm wide. Send us the pit layout and we will prepare a cover layout drawing showing the frame sections, beam positions and slide-out direction. For guidance on beam centres, chamber design and loading class, see our guide to specifying access covers for large openings.
