3-1/2" Square Aluminum Fence Post Cap

3-1/2 Inch Square Aluminum Fence Post Cap

This 3-1/2 inch square aluminum fence post cap gives fence fabricators and maintenance buyers a defined option for square posts that do not belong in a four-inch cap schedule. It can support new-build or replacement procurement for perimeter and gate posts, provided the nominal size is checked against the real post profile before bulk production.

Procurement Basis

Separate Nominal Size From Actual Geometry

The nominal 3-1/2 inch callout is only the start of compatibility review. Measure from outside face to outside face in both directions and note rounded corners, seam location, top-edge deformation, coating thickness, and any internal obstruction. A cap selected from one number can still bind, rock, or sit high when its mating geometry is different from the installed post.

Replacement Survey for Mixed Fence Runs

Older properties may contain several post generations even when the fence appears visually consistent. Mark sample posts at ends, corners, gates, and intermediate runs, then compare their dimensions. Record how many caps belong to each verified group. This prevents a maintenance buyer from mixing a correct 3-1/2 inch requirement with nearby posts that need another size or a custom detail.

Material and Coating Coordination

Aluminum offers low piece weight and resistance to red rust, but project durability still depends on finish, drainage, installation, and the surrounding assembly. For natural mill finish, agree on the acceptable appearance. For powder coating, provide the color reference, gloss, exposure, and handling standard. Where aluminum meets coated steel or another metal, ask the responsible project team to review material contact and water retention.

Sample Approval and Packing Plan

A physical sample can confirm fit and visible proportions before the purchase order moves into volume production. Identify the post used for approval and keep the accepted drawing or sample reference with the order. For shipping, define counted inner bags or dividers, labeled cartons, finish protection, maximum carton weight, and marks that connect each carton to the correct phase or site.

Information Needed for an RFQ

Provide measured post dimensions, post material, photographs, cap quantity, desired finish, color, intended attachment, sample quantity, packing instructions, destination, and schedule. Eone Industry can review the 3-1/2 inch square aluminum cap against the supplied post information, coordinate compatible hardware, and quote production together with consolidated packing and door-to-door delivery options.
