Attachment 5 Shim Dimensions.png

This is a technical drawing specification for a rubber seal bottom assembly component. The document, labeled as Figure F1 and drawn to a scale of 3" = 1'0", details the design and installation requirements for a bottom seal assembly mechanism. The drawing illustrates an existing bulkhead structure with a rubber seal shim that must be provided. The assembly includes a round edge bar measuring 3" X 1/2" with an existing 11/16" bolt hole, positioned with specific dimensional clearances including a 3/4" width dimension and a 1/4" radius specification. The rubber seal at the bottom is sized with a 2" dimension and must include a PTFE (polytetrafluoroethylene) material component. The assembly requires precise positioning relative to the existing bulkhead structure, with measurements indicating a 3 1/4" vertical dimension and clearances of 1/16" gaps at critical points.

The drawing specifies material requirements and finishing standards for the bottom seal assembly, requiring proper integration with existing structural elements. The rubber seal shim must be installed in a manner that maintains alignment with the bulkhead structure while accommodating the round edge bar attachment. All dimensional tolerances and material specifications shown are critical for proper functionality and weatherproofing performance of this structural seal application.
