Survey New and Existing Tube Conditions

For new fabrication, measure samples from the actual tubing lot. For repair work, inspect several posts because paint, zinc buildup, weld repairs, dents, and flare may differ by fence run. Record both axes and corners. Define the accepted engagement and movement so crews do not force a cap onto a damaged or oversized tube.

Plan Installation Access

Identify rails, brackets, hinges, internal reinforcements, welds, and top accessories before setting the cap detail. Decide whether the cap remains removable for inspection or service. It can finish the open post and reduce direct debris entry, but it is not a watertight seal, lifting eye, tie-off, or structural closure.

Approve Visible Finish Quality

Choose and document the galvanized process and optional powder coating. Confirm color, gloss, texture, acceptable handling marks, and repair limits. At this size, coating differences may be visible at the top of a fence line. Test final-finish clearance and avoid promising maintenance-free or corrosion-proof performance without project-specific terms.

Protect Corners During Freight

Use dividers or controlled nesting to prevent corner dents and skirt spreading. Establish pieces per inner pack, carton weight, finish labels, lot, pallet support, and destination marks. Keep 3-1/2 inch stock apart from 3-1/8 inch caps. Do not place dense loose hardware above unsupported cap profiles.

Receiving and Installation Check

Check dimensions, diagonal, square form, edge, approximate weight, coating, labels, and quantity from each lot. Fit-test on the approved tube before branch or crew distribution. Confirm attachment and surface repair. Photograph transport damage and quarantine distorted pieces instead of correcting them with uncontrolled impact.
