Product Description
Catalyst Seaside 5" x 5" Vinyl Posts – Routed Supports for Seaside Louvered Fence
- Seaside-specific routing – Pre-routed posts engineered to accept Seaside’s horizontal louvered boards directly, with no brackets or rails required.
- Multiple post functions – Choose from 5" x 5" line, left end/gate, right end/gate, and 6" x 6" inside and outside corner posts to match every point in your fence run.
- Full 102" length – Extra-long posts provide plenty of depth for secure installation while maintaining the full 6' panel height above grade.
- Clean, modern look – Pre-routed design keeps hardware hidden so the finished fence shows only sleek Seaside louvers and posts.
- Built for Seaside performance – Works with the Seaside 6' x 6' semi-private louvered panels and matching gates for consistent wind performance and airflow.
Catalyst Seaside 5" x 5" vinyl posts are purpose-built for the Seaside 6' x 6' semi-private horizontal louvered fence system. Each post is factory-routed so the 13 louvered boards lock directly into the post channels, creating a clean, rail-free look that still delivers the privacy, airflow, and wind performance Seaside is known for. Available in several routing patterns—line, left end/gate, right end/gate, and heavy-duty 6" x 6" inside and outside corner posts—these 102" long posts give you the flexibility to lay out straight runs, corners, and gate openings while keeping the fence style perfectly consistent from end to end.
Why Choose These Seaside Posts
- Matched to Seaside panels – Designed specifically for the Seaside 6' x 6' louvered fence section so the louvers fit correctly and lock into place.
- Pre-routed for faster installs – No brackets to align or extra hardware to buy; simply set the posts, then feed the louvered boards into the routed channels.
- Flexible layout options – Dedicated line, end/gate, and corner posts make it easy to transition between straight runs, corners, and walk or drive gates.
- Consistent height and spacing – Standardized 102" length and factory routing help maintain a uniform 6' fence height and board spacing across your project.
- Low-maintenance vinyl – Vinyl construction resists rot, rust, and insect damage and requires only occasional cleaning to look its best.

Installation
- Plan your layout first, marking post locations with stakes and string, including any gate openings and corners.
- For 5" x 5" posts, dig post holes approximately 10" in diameter, down to your local frost line, and add 6" of gravel at the bottom for drainage.
- Set each post so the finished Seaside panel will sit about 2" above grade, then backfill with concrete and plumb the posts as you go.
- Install Seaside louvered boards by inserting each board into the routed channels of one post, then flexing them into the opposite post, working from the bottom up until all 13 boards are in place.
- At gate openings, use the appropriate left or right end/gate post and install any required gate post inserts or reinforcement according to manufacturer guidelines and local codes.
- Finish by gluing post caps onto each post and allowing concrete to cure fully before hanging gates or applying load to the fence.
Buying Guide
Choosing the correct Seaside post type is critical because the louvered boards lock directly into the post routes, and there are no separate rails to adjust. Use this quick reference to match each post to its ideal location in the fence run.
| Post Type | Size | When to Choose This Post |
|---|---|---|
| Line Post | 5" x 5" x 102" | Use between two Seaside 6' x 6' louvered panels in a straight run of fence. |
| Right End/Gate Post | 5" x 5" x 102" | Use at the right-hand end of a fence run or on the right side of a Seaside walk or drive gate opening. |
| Left End/Gate Post | 5" x 5" x 102" | Use at the left-hand end of a fence run or on the left side of a Seaside walk or drive gate opening. |
| Inside Corner Post | 6" x 6" x 102" | Use where the fence turns an interior 90° corner and the louvered boards need to turn inward around the corner. |
| Outside Corner Post | 6" x 6" x 102" | Use where the fence turns an exterior 90° corner and the louvered boards wrap around the outside of the corner. |
- Match post routing to your layout. Every post is routed specifically for its role; mixing post types can prevent the louvered boards from locking properly.
- Account for gate reinforcement. Plan for any gate post inserts or additional bracing at walk and drive gates, especially in high-wind or high-traffic areas.
- Order caps with posts. Pair Seaside posts with compatible 5" x 5" or 6" x 6" post caps to protect the hollow post interior and finish the look.
- Check local codes. Verify post depth, spacing, and any special requirements for wind or pool barriers before installation.
- Order all components together. Combine Seaside panels, posts, gates, and caps in a single order to ensure matching inventory and color lot.
Frequently Asked Questions
Do Seaside posts come pre-routed for the louvered boards?
Yes. All Seaside posts are pre-routed so the horizontal louvered boards lock directly into the post channels, eliminating the need for separate rails or brackets.
How long are the Seaside posts, and what height fence do they support?
Seaside posts are 102" long and are designed for use with 6' x 6' Seaside louvered fence panels, providing enough embedment for in-ground installation while maintaining a 6' finished fence height above grade.
Which post should I use at a corner of my Seaside fence?
Use the 6" x 6" Seaside inside or outside corner posts wherever the fence changes direction at a 90° angle; these posts are routed so the louvered boards can transition cleanly around the corner.
What posts do I need at a Seaside gate opening?
Use the 5" x 5" left and right end/gate posts on either side of Seaside walk or drive gates. These posts are routed to accept the louvered boards and provide the proper configuration for gate hardware and openings.
Are Seaside panels, gates, and post caps included with the posts?
No. Seaside posts are sold individually; panels, gates, post caps, and any gate reinforcement inserts are sold separately so you can order exactly what your layout requires.
Can I cut Seaside posts to a shorter length?
Posts can be cut down in the field if needed, but you must maintain sufficient embedment depth in concrete and keep the routing aligned to the finished fence height; always follow the manufacturer’s installation instructions and local building codes.
