A seal arrangement for a surface access assembly

摘要

A surface access assembly (10) comprises a frame (12) defining an opening (18), a cover member (14) mountable on the frame in the opening and a sealing member (26) for providing a seal between the frame (12) and the cover member (14). The sealing member (26) includes a first part (30) and a second part (28), the second part (28) being relatively more deformable in use than the first part (30).
