Catalyst 5" x 5" Fence Posts for Hudson & Montauk Semi-Private Fence Styles are the system posts used with Hudson 6" Semi-Private and Montauk semi-private board-on-board vinyl fences. At 108" long, these White vinyl posts are sized for 6' panel heights, providing the extra length needed for proper burial in concrete footings. The 5" x 5" profile is used for line, corner, end, and gate posts, giving you a consistent structural and visual foundation across the entire fence run. Pair these posts with Hudson or Montauk semi-private panels, matching gates, compatible 5" x 5" caps, and any required post inserts to complete a durable, low-maintenance fence system.
Why Choose This
- Made for Hudson & Montauk systems — These 5" x 5" x 108" posts are listed in the Hudson and Montauk semi-private fence system specifications for 6' panels, helping ensure a proper fit.
- Proper length for 6' fences — 108" posts give you extra length below grade so the fence can be set securely in concrete for long-term stability.
- Single color, easy matching — Supplied in White only, simplifying color selection and ensuring consistent appearance with Hudson and Montauk White panels and gates.
- Versatile post roles — The same 5" x 5" post size is used as line, corner, end, and gate posts when paired with the correct routing and inserts.
- Low-maintenance vinyl — Vinyl posts won’t rot, peel, or require repainting; routine rinsing is typically all that’s needed.
- Compatible with 5" x 5" caps — Works with a range of 5" x 5" decorative caps (such as pyramid, New England, and Gothic styles) to finish the look.

Installation
Lay out your Hudson or Montauk semi-private fence run and mark post locations based on 6' panel heights and system-specific panel widths. Set each 5" x 5" x 108" post in a concrete footing deep enough to accommodate local frost depth and wind conditions, leaving enough post height above grade for a 6' panel plus any ground clearance. Ensure posts are plumb and aligned before attaching rails and panels. Where gates will be installed, use suitable 5" x 5" post inserts and gate hardware rated for the opening width and weight. Finish by installing matching 5" x 5" caps on all posts.
Buying Guide
- Count posts by panel runs — Plan on one post between each panel section, plus an additional post at each end of the run and on either side of any gate opening.
- Plan for gates — Each single gate needs two posts; double-drive gates need two hinge posts and may use existing line posts depending on layout and hardware.
- Stay with system components — Use these posts only with compatible Hudson and Montauk semi-private components to maintain fit and performance.
- Select matching caps and inserts — Order 5" x 5" caps and any necessary post inserts at the same time as posts to avoid delays in installation.
- Confirm White finish — These posts are available in White only, which simplifies color selection and ensures consistent appearance with White Hudson and Montauk panels.
