Abstract
Insert (10) is formed from sheet (12) which is slidably held in slit (16) formed in compressible resilient covering (14). Stiffening member (22) is contained in the core of material (14) and has a slit (24) also slidably holding sheet (12). A compressible resilient insert (90) is contained in stiffening member (22). Corner members (26) slidably engage adjacent stiffening member (22) and sheet (12). Insert (90) and covering (14) compressibly hold sheet material (12) in frame (60). Fasteners (30) are used to urge members (22) toward frame (60) thereby further compressing member (14) to close any gaps with frame (60). A quadruple sealing effect is achieved as a result of: 1) the insert (90) between edge (15) and member (22); 2) the clamping action of member (22) on sheet (12); 3) the clamping action of covering (14) on sheet (12); and 4) the compression of covering (14) between frame (60) and member (22).
