3-1/8" Square Galvanized Steel Fence Post Cap

3-1/8 Inch Square Galvanized Steel Fence Post Cap

The 3-1/8 inch square galvanized steel post cap is identified by a 3.125 inch nominal profile and a listed approximate mass of 0.12 kg. It is intended for compatible square posts used in fencing, gates, terminal work, repairs, or custom fabrication. This uncommon fractional size needs decimal labeling and physical separation from 3 inch caps throughout procurement and field distribution.

Approve the 3.125 Inch Interface

Measure both post sides, the diagonals, corner radius, seam, and final coating. Write 3.125 inches on the approval sample. Check engagement depth and retention without forcing the cap. Do not issue this item to a 3.000 inch post group unless a controlled fit test and revised installation method have been approved.

Maintain Fractional-Size Traceability

Connect each carton to a post schedule, work area, or replacement asset list. Older fabricated systems may use dimensions that are not obvious from drawings, so verify field posts from more than one location. The cap completes the visible top but does not correct post distortion or serve as a structural connection or personnel anchor.

Evaluate Coating at Final Dimension

State pre-galvanized, hot-dip galvanized after fabrication, or powder-coated-over-galvanized requirements. Approve surface appearance, color, gloss, and repair procedure. Zinc and powder buildup can affect a fractional fit. The production sample should carry the intended treatment and should be checked on the actual post source before the lot is released.

Print 3-1/8 and 3.125 on Labels

Use both formats plus SKU EONE-FPC-SQ-3125 on every inner pack and carton. Separate it from 3 inch and 3-1/2 inch caps with divided pallet zones. Define pack count, gross weight, separators, finish, lot, and destination. Avoid handwritten labels that omit the eighth-inch fraction.

Receiving and Installation Check

Receiving inspection should verify fraction, decimal, two side measurements, corners, approximate weight, coating, count, and lot. Fit-test against the approved 3.125 inch post. Retain a signed sample for repeat orders and isolate any cap that is oval, twisted, dented, or unable to seat evenly.

3-1/8 Inch Square Cap RFQ

Provide actual tube dimensions, quantity, finish, attachment, sample need, labeling rules, destination, and schedule. Eone Industry can coordinate fit review, production, quality control, and door-to-door air or sea freight.

Surface treatment options: Pre-galvanized / Hot Dip Galvanized / Powder Coated. Confirm the required finish, color, gloss, coating build, touch-up method, and final fit allowance before production. These options should be selected in the RFQ instead of treated as interchangeable stock finishes.
