Removable Curb Lid

Removable Curb Lids for Industrial Buildings

R&S Removable Curb Lids for access to equipment inside large industrial buildings. High-grade aluminum construction keeps the lids lightweight, thus easy to maneuver at roof level. Slots along the mounting rails accept heavy gauge hardware for a solid and secure fit. Together with high density bulb gaskets along perimeter, these lids stay locked in place, sealed and dry.

These lids compliment the overall architectural appeal of any roof system. Lids have a mill aluminum finish for an industrial look. Otherwise, they may be painted to match the roof color.

Durable Design = Long Service Life

I-Beam construction and cross-members in particular provide industry-leading strength and durability. Integral eye-bots act as lifting points via a crane. Lid tolerance is 10 PSF and can meet heavier live loads as specified. Maximum lid size is 10′ x 20′.

All lids integrate with any  R&S Roof Curb or an existing curb on site.
