- Premium Aerospace-Grade Aluminum: Our 4x4 post base cover is crafted from high-strength aviation-grade aluminum alloy. Its surface undergoes chemical pretreatment followed by UV-resistant powder coating at high temperatures, delivering waterproofing, corrosion resistance, UV protection, and salt/alkali tolerance. It withstands diverse climate tests. An optional dedicated rainproof rubber seal efficiently blocks rainwater from entering the post shaft, safeguarding the post base from rust.
- Split-Design Installation: The 4x4 post cover features an innovative two-half structure. Installation requires no removal of existing columns—simply snap it into place to seamlessly conceal anchor points, screw holes, concrete residue, and other base imperfections. Shields against pest damage and moisture penetration as a protective 4x4 post skirt and decorative post base trim, preventing costly repairs.
- Precise 4x4 Post Compatibility: Engineered for standard 4x4 posts (fits 3.5x3.5 to 4x4 wooden/metal posts). Covers 4-inch height (10cm), Quantity: 2-piece set
- Quick & Easy Installation: Includes specialized connecting brackets and stainless screws. Simple 3-step process: ① Clamp split cover around post base → ② Insert brackets and tighten → ③ Reinforce and snap cover strip. Single-person operation requires no specialized tools, saving time and effort.
- Universal post Protector: This 4x4 post sleeve suitable for deck post base, gazebo columns, porch pillars, patio columns, fence railings, lampposts, mailbox posts, and carport supports. Compatible with pine, teak, steel, aluminum, and other materials, delivering industrial-grade corrosion protection and decorative solutions in one as a versatile 4x4 post wrap and post cap.
- 4×4 Aluminum Post Base (Actual Size 4" × 4") accommodates posts ranging from 3.5×3.5 inches to 4×4 inches in actual dimensions. When your post measures 3.5" × 3.5", pair it with our included 3.5-inch waterproof rubber seal ring. This seal fills any excess gap to prevent rainwater from directly entering the post base. If installing on an actual 4-inch × 4-inch post, no rubber seal is required. You may seal minor gaps yourself using a small amount of outdoor weatherproof sealant or waterproof adhesive. Note: Only the 4×4 Post Base Cover (actual size 4"×4") includes the 3.5-inch dedicated waterproof rubber seal.
