PDS Construction - Sealed Joints
CS-04.02.02
CAT II
10
1. All PDS seams and connectors must be permanently sealed completely around all surfaces (e.g., welding (continuous or track), epoxy, fusion).
2. When a connection consists of more than one seam (e.g., a compression couple), then all seams must be sealed.
3. The seal must provide a mechanical bond between the components of the carrier and are visible for inspection.
4. Epoxy seals must use a thick, opaque material.
5. Couplers that are secured with a “set screw” must not be used.
6. If pull boxes are used during installation, the pull-box covers must be secured/sealed to the pull boxes by welding or epoxy after installation.
7. If welded, at least one weld must be applied on each side of the box and cover.
8. If epoxy is used, it must be applied between all mating surfaces continuously around the cover.
9. Painted surfaces must be treated to form a mechanically strong epoxy bond.
10. Boxes with pre-punched knockouts must not be used under any circumstances.
NOTE: If a pre-fabricated (Modular types such as Holocom or Wiremold) PDS is used it is also required to have all joints sealed as specified above.
Check to ensure:
1. All PDS seams and connectors are permanently sealed completely around all surfaces (e.g., welding (continuous or track), epoxy, fusion).
2. When a connection consists of more than one seam (e.g., a compression couple), then all seams must be sealed.
3. The seal provides a mechanical bond between the components of the carrier and are visible for inspection.
4. Epoxy seals use a thick, opaque material.
5. Couplers that are secured with a “set screw” are not used.
6. If pull boxes are used during installation, check that the pull-box covers are secured/sealed to the pull boxes by welding or epoxy after installation.
7. If welded, at least one weld must be applied on each side of the box and cover.
8. If epoxy is used, it is applied between all mating surfaces continuously around the cover.

10. Boxes with pre-punched knockouts are not used under any circumstances.
