Regal Textured Black End Post 2-1/4″ x 42″

Worth it for contractors who need code-compliant aluminum posts that install without field drilling. The welded brackets save real time on multi-unit projects, and the 20-year commercial warranty backs up the durability claims. At 3.60 lbs, crews handle these posts all day without fatigue.

Skip it if you’re just doing basic residential decks with wood posts. This aluminum system costs more upfront than pressure-treated 4x4s. The real value shows up on commercial jobs where meeting NBC and IBC requirements for buildings up to 12 stories matters.

The Pre-Welded Advantage

Regal welds the upper and lower brackets right to the post at the factory. No measuring bracket placement. No drilling pilot holes. No field-bolting brackets that might loosen over time. You position the post, secure the base plate, and slide in your rails.

The 4” x 4” aluminum base plate comes pre-attached. ACQ-treated versions handle Montana’s wet springs better than standard aluminum — that copper-based treatment prevents galvanic corrosion when aluminum meets treated lumber.

Installation breaks down to four steps:

1. Position the base plate and secure to the deck surface with appropriate fasteners
2. Slide the post onto the base plate (if not pre-welded)
3. Align and secure railing sections into the pre-welded brackets/sleeves
4. Snap on the post cap for a finished look

Tools needed: drill/driver, level, measuring tape, socket set/wrench, and your deck fasteners. No specialty equipment. No bracket jigs. No field modifications.

Built for Commercial Standards

Specification	Value
Material	100% high-strength extruded aluminum alloy
Dimensions	2-1/4” x 2-1/4” x 42” H
Weight	Approx. 3.60 lbs
Finish	Premium UV-powder-coat (Textured Black)
Base plate	4” x 4” aluminum (standard or ACQ-treated)
Warranty	20-year limited structural (residential and commercial)

The UV-powder-coat finish resists corrosion, fade, chip, and crack — critical for Montana’s temperature swings and high-altitude UV exposure. Designed for residential, commercial, and multi-family projects up to 12 stories, these posts exceed typical deck railing requirements by a wide margin.

The welded rail sleeve and 6-inch square aluminum base plate provide secure attachment while meeting or exceeding national building codes. That commercial-grade engineering matters when your project faces real liability exposure.

System Compatibility

These end posts work with Regal Picket and Tempered Glass systems. Compatible components include Regal Line Posts, Corner Posts, and Stair Posts, plus Post Caps (Ball, Pyramid, Tower), Base Plate Covers (BC-TB), and specialty brackets like SideMount or CornerMount.

The snap-on post cap comes included — no separate purchase needed. Also available in White, Bronze, and Black (non-textured) to match your project specs. Height variants include 36” posts for standard residential height and 60” posts for pool/wind-wall applications.

For heavier-duty applications, 4x4 Post Profile versions (RP4E, RP4C) offer a larger, more robust alternative with a 6” base plate. Choose based on your load requirements and aesthetic preferences.

Frequently Asked Questions

Q: What makes these posts suitable for Montana’s climate?

A: The UV-powder-coat finish ensures durability in all climates, handling Montana’s freeze-thaw cycles and intense high-altitude sun. The ACQ-treated base plate option provides superior corrosion resistance for areas with spring snowmelt and wet conditions. The 20-year warranty covers manufacturing defects and finish issues including rust, fade, chip, and crack under normal use conditions.

Q: How much time do the pre-welded brackets actually save?

A: Eliminating the need for field drilling or bolting of brackets cuts significant time on every post. Figure 10-15 minutes saved per post when you factor in measuring, marking, drilling, and bolting brackets. On a 200-foot commercial deck with posts every 6 feet, that’s 5-8 hours of labor saved.

Q: Can these posts handle commercial building codes?

A: Yes. These posts meet or exceed National Building Code (NBC) requirements and International Building Code (IBC) requirements. They’re approved for residential, commercial, and multi-family applications up to 12 stories — far exceeding typical deck post requirements.

Q: What’s included with each post?

A: Each post includes the 2-1/4” x 42” aluminum post itself, a standard snap-on post cap, welded rail sleeves/brackets, and the 4” x 4” aluminum base plate pre-attached. You supply the deck fasteners appropriate for your substrate.

Q: How does aluminum compare to pressure-treated posts for longevity?

A: The 100% high-strength extruded aluminum alloy construction won’t rot, warp, or crack like wood. No annual staining. No checking or splitting. The 20-year warranty reflects real-world durability — most pressure-treated posts need replacement within 10-15 years in Montana’s climate.
