Common questions about post kit.
The Standard PVC Post Kit includes 8-foot vertical PVC posts. We recommend installing the posts in holes approximately 24 inches deep for proper stability, resulting in a finished height of about 6 feet above ground.
Yes. Our Standard PVC Post Kit is designed for outdoor use and is rain resistant, rust resistant, and rated to withstand winds up to 55 mph when properly installed.
Our headquarters is in Fort Lauderdale, Florida, so we design our post kits with harsh weather conditions in mind.
Yes. While the Standard PVC Post Kit is commonly used with 4′ × 4′ and 4′ × 8′ signs, we can manufacture custom sizes to accommodate other sign dimensions.
For custom configurations, please call us at 1-800-843-7446 or email mail@1800thesign.com for details.
All post kits for 4‘×8‘ signs are designed for use with 10mm corrugated plastic only.
PVC Frame installation typically takes 30–45 minutes. The sign slides into horizontal tracks, which are secured to two vertical posts using the included hardware. The posts can be installed by digging 18"–24" deep holes or by using T-posts and a post pounder for hard or frozen ground.
Arrow Post Kits typically install in 30–45 minutes and are designed to display two single-sided signs in a V-shape for maximum visibility. The signs slide into horizontal tracks and are secured to three vertical posts (one center post and two side posts). Posts are installed by digging 18"–24" deep holes, using the sign as a spacing guide.
Yes. Gothic caps are available as an elegant alternative to standard flat caps for all post kit options. You may also request holes (for 10mm signs) or brass-plated grommets (for 4mm signs) for hanging, or mount the sign directly to a wall by drilling through the corrugated plastic.
Self-Standing Post Kits typically install in 30–45 minutes and are designed for hard surfaces such as asphalt or concrete. The vertical posts attach to a flat base, the sign slides into horizontal tracks, and stabilizers with sandbags are used to add weight and keep the sign secure—no digging required.
If you are using your own wood frame (not sold by 1-800-THE-SIGN), the sign can be mounted to a custom-built frame using standard lumber and fasteners. The frame is typically set in 18"–24" deep holes, and the sign is secured directly to the frame using nails or screws. This option is best for permanent or long-term installations.
Wind resistance and return policy details.
4′×4′ and 4′×8′ signs in our PVC post kit hold up to about 55 MPH winds. Smaller signs with skirt stands hold up to about 45 MPH winds.
Our signs are printed with UV-resistant inks designed to withstand direct sunlight and maintain vibrant color for at least two years. Each design is produced on high-quality vinyl and finished with a durable, pressure-sensitive laminate for long-lasting protection and secure adhesion.
We do not accept returns on custom signs. Unused post kits and stands may be returned minus a 15% restocking fee. Return shipping is the customer’s responsibility (we can arrange return shipping upon request).
