Century Maxum 4″ Post

Century’s Maxum 4″ Post delivers true 4-inch wide aluminum construction with no exposed welds, giving contractors a heavier post that’s 100% compatible across all Century railing systems. The true 4” x 4” (102mm x 102mm) dimensions and 9.2 lb weight create a more substantial visual presence than standard posts, while professional-grade engineering meets IRC and IBC code requirements for both residential and commercial applications.

Universal Compatibility Across Century Systems

The Maxum eliminates adapter headaches. It’s 100% compatible with Century Picket Railing, Century Glass Railing (both component and scenic systems), and works with secondary handrails and swivel/wall brackets. This matters when you’re stocking posts for multiple job types or switching between picket and glass infill on the same project.

Unlike standard posts that may require separate adapters for certain configurations, the Maxum is designed for universal compatibility across all Century systems. Corner installations where handrails connect? No problem. Mixed system installations? The Maxum handles them all.

Compared to the standard 2.5” Century post, the Maxum 4” post offers increased structural weight (9.2 lbs vs ~4 lbs). That extra mass isn’t just for show — it provides genuine stability for commercial applications and high-traffic residential decks.

Virtually maintenance-free construction requires periodic cleaning with mild soap and water to maintain the powder-coated finish. No annual staining. No rot replacement. Just occasional washing when pollen or dirt builds up.

Professional-Grade Warranties

Century backs the Maxum with warranties that matter for contractor reputation:

• 20-year limited warranty against structural defects
• 5-year limited warranty on the powdercoat paint finish

Twenty years of structural coverage in Montana’s freeze-thaw cycles and UV exposure says something about the engineering. The powder coat warranty covers the realistic service life before most homeowners consider aesthetic updates anyway.

Frequently Asked Questions

What fasteners should I use for Maxum posts?

Typically installed using heavy-duty lags or screws appropriate for the substrate (wood or concrete). Match your fasteners to your deck material and local code requirements.

Does the Maxum 4” post work with older Century railing sections?

The post is 100% compatible with Century Picket Railing and Century Glass Railing (both component and scenic systems). If you’re running Century rails, the Maxum will connect.

What’s included with each post?

The post (4” x 4”) comes as the primary component, with optional accessories sold separately including base plate covers, post skirts, and pyramid-style post caps. Check with your supplier about fastener inclusion — some dealers bundle them, others sell separately.

How does the weight compare to standard posts?

The Maxum offers a much more substantial visual presence and increased structural weight (9.2 lbs vs ~4 lbs) compared to the standard 2.5” Century post. You’ll feel the difference when handling them, and homeowners see the difference in the finished project.
