PosterSpring is a versatile, spring-loaded system designed to securely hold posters on all types of billboard panels, including 30-sheet and 8-sheet formats, both new and old. Its narrow design fits easily under stretch-face trim, and it works on panels with radius corners or older retro designs. The springs also function on molding-less panels, providing a secure hold without needing to remove or replace trim. PosterSpring makes poster changes faster and easier by using tension to hold the poster in place, eliminating the need for screws or complex mounting hardware. This system offers a quick, efficient solution for outdoor advertising, even in more challenging panel configurations.
Very easy, no need to remove or replace trim, molding, or brackets. Lind Outdoor converted 90% of its poster plant without removing molding. A billposter with a cordless drill, tape measure and 48 PosterSprings is all that is required.
PosterSpring is the most eco-friendly system on the market. PosterSpring is the only system that enables easy rotation and re-use of SSPs. "One and done" does not have to apply when using the system.
Made in Ohio from durable, engineered stainless steel, each PosterSpring is designed to hold between 4 and 18 lbs of constant tension, functioning as part of an overall system of springs. The entire system contains no plastic components, ensuring long-lasting durability and reliability. If a spring ever needs replacing, it’s as simple as swapping out an individual spring, making maintenance easy and cost-effective. This robust design ensures that posters remain securely mounted without the need for complicated or fragile parts.
Just drill small holes into the side of the molding at specified 18" intervals. Can we still post glued posters and install premier vinyl wraps after installing PosterSpring? Absolutely, PosterSpring is installed completely beneath the molding and does not protrude into the posting surface and display area when not in use. Further, vinyl wraps can be accomplished just as before as PosterSpring is completely contained beneath the molding.
None. Drop shipped posters for local and national buys go directly from the shipping box to the poster panel with absolutely no prep time. No gripper bars, cables or clips required.
PosterSpring has provided amazing success on the sales side of our business because our poster and bulletin plants look awesome. Tight, wrinkle free postings equal happy advertisers. The ability to re-use and rotate single sheet posters has lowered production costs for our advertisers, enabling them to increase ad-spend in outdoor space. PosterSpring delivers lower production costs which provide a competitive advantage versus other outdoor operators and other media formats in general.
PosterSpring has enabled Lind Outdoor to increase billposting ability by 60%, while enabling increased efficiency overall. We have been able to transfer personnel to construction, maintenance and vegetation control that has enabled us to elevate the quality, size, and condition of our plant.
PosterSpring can be incorporated into any billboard operation with existing trim, available in 3", 6" and 11" lengths to fit any billboard molding. Once installed, no tools are needed for posting. We are not aware of a better billboard posting system.
