About this item
- ROUNDED SAFETY CORNERS — SAFE ON DECK RAILINGS. Unlike caps with sharp square corners that scratch hands or snag clothing, ours are smoothly rounded — a safer choice anywhere people reach past them, and ideal for homes with kids and pets.
- HEAVY CAST ALUMINUM — SOLID, NOT THIN & STAMPED. Thick cast aluminum that feels substantial in hand, noticeably heavier than the hollow stamped caps others ship. Won't dent, crack, warp, or rust-streak your posts. Built to last decades outdoors.
- DEEP-SEAT DESIGN + STAINLESS STEEL SCREWS. Seats deeper onto the post than shallow caps for a secure grip that won't rattle or blow off, and includes rust-proof stainless steel screws that won't streak or strip. Install once and leave it.
- PRECISE FIT — STANDARD 4×4 POSTS (ACTUAL 3.5" × 3.5"). MEASURE FIRST. Fits standard/nominal 4×4 wood posts, which actually measure 3.5in × 3.5in. Will NOT fit a full 4in post — order the 4×4 cap for those. Opening guides on easily, then seats snug. Always measure the top of your post before ordering.
- SD-GRADE POWDER COAT — ALL-WEATHER FINISH. Premium SD-grade powder-coated finish stands up to rain, snow, and UV without fading or peeling, for a clean, uniform look on decks, fences, pergolas, and railings.
