Its nominal size is familiar to many buyers, but the words four inch do not establish the actual outside dimension, inside clearance, corner geometry, or attachment detail needed for a reliable project fit.\u003c\/p\u003e\n\n  \u003ch3\u003eSpecified Product Data\u003c\/h3\u003e\n  \u003ctable\u003e\u003ctbody\u003e\n    \u003ctr\u003e\n\u003cth\u003eNominal size\u003c\/th\u003e\n\u003ctd\u003e4 inch square post cap\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eMaterial family\u003c\/th\u003e\n\u003ctd\u003eAluminum fence hardware\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eSurface choices\u003c\/th\u003e\n\u003ctd\u003eMill finish or project-specified powder coating\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eApproximate piece weight\u003c\/th\u003e\n\u003ctd\u003e0.13 kg \/ 0.29 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eItem code\u003c\/th\u003e\n\u003ctd\u003eEONE-FPC-SQ-AL-4000\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eBuyer type\u003c\/th\u003e\n\u003ctd\u003eFence contractor, fabricator, dealer, distributor, or project purchaser\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\u003c\/table\u003e\n\n  \u003ch3\u003eNew Construction and Replacement Orders\u003c\/h3\u003e\n  \u003cp\u003eFor a new fence package, coordinate the cap with the selected post profile before fabrication begins. For replacement work, inspect the existing post line instead of relying on an old invoice or a field description. Posts sold under the same nominal label can differ in radius, seam, wall thickness, or coating. A short sample approval step is usually cheaper than correcting a large cap order that was matched only by name.\u003c\/p\u003e\n\n  \u003ch3\u003eDefine the Required Cap Fit\u003c\/h3\u003e\n  \u003cp\u003eProvide the measured outside faces of the square post, the condition of the top edge, and a photograph or profile drawing. State whether the cap covers the exterior, fits into the opening, or uses a project-specific connection. Do not assume a press fit, adhesive, screw, weld, or other fixing method unless it appears on the accepted drawing. Confirm clearance for paint, powder coating, galvanizing, and normal production tolerance.\u003c\/p\u003e\n\n  \u003ch3\u003eChoose and Control the Surface Finish\u003c\/h3\u003e\n  \u003cp\u003eUse mill finish when natural aluminum is acceptable or when finishing will be completed later under the buyer's control. A powder-coated order should identify the color standard, gloss, visual acceptance sample, service environment, and packaging protection. If caps must match posts, gates, and panels supplied in separate production batches, approve the finish reference and acceptable variation before manufacturing.\u003c\/p\u003e\n\n  \u003ch3\u003eInstallation-Phase Quality Control\u003c\/h3\u003e\n  \u003cp\u003eKeep caps in labeled cartons until the related post area is ready. Check a small number against dry, clean posts before opening every carton. The installer should look for interference from burrs, deformed post corners, weld spatter, excess coating, and water trapped inside the post. Any field alteration should follow the project-approved method so it does not damage the cap or surrounding finish.\u003c\/p\u003e\n\n  \u003ch3\u003eCommercial Quote Checklist\u003c\/h3\u003e\n  \u003cp\u003eFor pricing, send the 4 inch post drawing or actual measurement, total cap quantity, finish selection, color, sample need, attachment detail, carton labeling, destination, unloading limits, and required delivery date.
