CityPost

CityPost makes patented cable railing systems designed specifically for do-it-yourselfers who want professional results without hiring a contractor. The company was developed by 3 friends with a passion for building better, more efficient solutions, aimed at making residential renovations easy and affordable.

Their cable railing kits work for decks, patios, stairs, and balconies. The systems handle residential decks, patios, balconies, stair railings for interior and exterior, commercial applications requiring 42” heights, and horizontal-to-stair transitions. Everything comes in complete kits — posts, rails, cable, and hardware included.

Cable Railing Components and Montana Performance

CityPost offers two main post material options that matter for Montana’s climate. The standard option uses 14-gauge zinc-plated (galvanized) steel posts with powder-coated finish (typically Black or White). The powder-coated finish is designed for exterior durability, with optional stainless steel posts for installations within 5 miles of saltwater.

For Montana builders, that zinc-plated steel option makes the most sense. You’re not dealing with saltwater corrosion 500 miles inland. The powder coating handles freeze-thaw cycles and temperature swings better than bare metal ever could.

The cable specifications tell you what you need to know:

Specification	Value
Cable Material	1/8” Marine-grade 316 stainless steel
Post Heights	36 inches (11 cable holes), 42 inches (13 cable holes)
Post Spacing	Maximum 6 feet center-to-center
Cable Spacing	3 inches on-center (complies with the 4-inch sphere rule)
Top Rail	1” x 3” powder-coated aluminum, provided in 6 ft lengths
Extra Cable	10% extra cable included in every kit to facilitate tensioning

The hardware uses Marine-grade 316 stainless steel for superior corrosion resistance. That matters when you’re dealing with spring snowmelt keeping everything wet for weeks.

Top Rail Transition Sleeves for Complex Deck Layouts

Here’s where CityPost shines for contractors dealing with deck-to-stair transitions. Their transition sleeves come in powder-coated galvanized steel (CityPost) or powder-coated aluminum (Lowe’s), designed to fit 1”x2” (graspable) or 1”x3” (standard) aluminum top rails.

Each sleeve includes 4 self-tapping screws. Use cases include 90-degree horizontal turns on deck corners, straight transitions between two railing segments, upper and lower transitions from a horizontal deck rail to a staircase (straight or 90-degree angles), and 45-degree angle transitions for specialized deck layouts.

The sleeves solve a real problem. Without them, you’re custom-fabricating every transition. With them, it’s four screws and done. Colors available include Black, White, Grey, and Bronze — match your post finish.

Installation Requirements and Building Code Compliance

The CityPost system installs in three steps: laying out and installing posts, installing the top rail, and attaching and tensioning the cables. That’s not marketing fluff — the patented bracket system actually works.

Mounting hardware depends on your substrate:

Surface Type	Fastener Options
Wood	3-inch or 4.5-inch lag bolts
Concrete	3-inch, 4-inch, or 5-inch Titan concrete anchors

Components include post fasteners suitable for wood or concrete, top rail brackets, and transition sleeves. The patented reversible top rail bracket supports horizontal runs and stairs — one bracket type handles both applications.

For code compliance, the system meets the critical requirements. Cable spacing at 3 inches on-center complies with the 4-inch sphere rule. The system’s design emphasizes compliance with building codes, which is critical for safety and regulatory approval.

CityPost works for contractors who appreciate systems that install without drama. Many emphasize that it can be installed without extensive experience, drilling, or complicated hardware. The complete kits mean fewer supplier runs. The patented brackets mean less custom fabrication. For Montana deck builders dealing with short construction seasons, that efficiency matters.

Frequently Asked Questions

Q: What post spacing does CityPost allow for their cable railing systems?

CityPost cable railing systems allow a maximum of 6 feet center-to-center post spacing. The system comes with pre-drilled posts that make layout straightforward at this spacing.

Q: What materials are CityPost railing posts made from?

CityPost offers two post material options: standard 14-gauge zinc-plated (galvanized) steel with powder-coated finish, or upgraded 316 stainless steel posts recommended for installations within 5 miles of saltwater. The powder coating comes in Black, White, Grey, and Bronze finishes.

Q: Does CityPost include all the hardware needed for installation?

Yes, CityPost cable railing kits include 100% of components needed: posts, rails, marine-grade 316 stainless steel cable, hardware, and their patented top rail bracket system. The kits even include 10% extra cable length to make tensioning easier during installation.

Q: What fasteners does CityPost require for mounting to different surfaces?

CityPost systems mount to wood decks using 3-inch or 4.5-inch lag bolts, while concrete surfaces require 3-inch, 4-inch, or 5-inch Titan concrete anchors. All mounting hardware comes included in their kits.

Q: How do CityPost transition sleeves work for deck-to-stair connections?

CityPost transition sleeves are powder-coated galvanized steel or aluminum connectors that handle 90-degree turns, straight transitions, and deck-to-stair transitions using just 4 self-tapping screws per sleeve. The sleeves fit 1”x2” (graspable) or 1”x3” (standard) aluminum top rails and come in Black, White, Grey, and Bronze to match your posts.

Q: What’s the difference between CityPost’s 36-inch and 42-inch post heights?

CityPost’s 36-inch posts (residential height) have 11 cable holes, while their 42-inch posts (commercial height) have 13 cable holes. Both maintain 3-inch on-center cable spacing to comply with the 4-inch sphere building code requirement.
