Regis 2" Aluminum Ball Caps - Choose Your Color

Product Description

Regis 2" Aluminum Ball Caps — Choose Your Color

• Classic ornamental look — Rounded “ball” finial adds a timeless accent to 2" square fence and railing posts.
• Durable aluminum build — Lightweight, corrosion-resistant cap stands up to weather without rusting or flaking.
• Powder-coated colors — Factory finish delivers rich color, UV resistance, and a clean, uniform sheen.
• Made to fit 2" posts — Sized for most 2" x 2" ornamental aluminum posts used on residential and light commercial jobs.
• Easy install — Press-fit design; add a small bead of exterior-grade adhesive for a long-term hold (adhesive not included).

Finish your ornamental fence or railing with a detail that looks intentional from every angle. The Regis 2" Aluminum Ball Cap brings a classic, architectural profile that works with flat-top panels, spear-top styles, and gates alike, creating a cohesive look across the project. Because the body is aluminum, it resists corrosion in coastal, humid, and freeze-thaw environments far better than painted steel. The powder-coated finish adds color depth and durability, so the cap keeps its appearance with minimal upkeep. Whether you’re matching existing caps or upgrading from plain flat caps, this is a simple, high-impact upgrade.

Selecting the right size is easy: measure your post across the flats—if it’s approximately 2" x 2", this model is the intended fit. The cap slips over the post for a snug, press-fit installation that takes just minutes; a dab of exterior-grade construction adhesive at the corners is recommended for long-term security in high-wind or high-traffic areas. Use one cap per post for line, corner, end, and gate posts to keep the silhouette consistent across the run. For best results, clean any oxidation or debris from the post top before installing the cap. A steady push by hand usually seats it; use a soft mallet if needed to avoid marring the finish.

Specifications

Buying Guide

• Color matching — Choose the powder-coat color that complements your panels, gates, and hardware.

Frequently Asked Questions

How do I confirm this will fit my post?

Measure across the flats of your post with a tape or calipers. If it’s about 2" × 2", this cap is the correct size.

Do I need adhesive?

Press-fit is often sufficient, but a small bead of exterior-grade adhesive inside the cap provides extra insurance in windy or high-traffic areas.

Will these work on steel or vinyl posts?

They’re intended for 2" aluminum posts. If another material uses the same 2" square dimensions, the cap may fit; verify with a dry-fit first.

Can I paint the cap later?

The factory powder coat is durable and colorfast. If repainting is desired, follow paint manufacturer guidance for scuffing and priming powder-coated aluminum.
