Tactile Warning Delineator (“TWD”)
Trapezoid Raised Surface Device
Installed only by Licensed VANGUARD Installers
Trapezoid / Tactile Guidance Cues
The advantages to using the VANGUARD Raised Tactile Warning Delineator are clear:

All Vanguard / TWSI’s are liquid plastic applied products. We make them right there onsite. No one else does what we do. There are no gaps, no seams, no toe catchers, no bolts, no screws, and no places for weeds to grow in between tiles because….there are no tiles! This allows them not only to follow the existing contours of your applied surface, but as importantly, Vanguard’s raised surface products will continue to follow the contours of your surface, even as that surface contour changes over time.
And the bond to the surface is stronger than the surface we apply it on. How do we do it? Practice (we’ve been doing this since 1994).
Because Vanguard products are installed using liquid plastic, Vanguard products “become one” with the surface, conforming to every nuance of the applied surface. The material is the adhesive.
Every micron is attached. And with Vanguard, every micron is always nonskid.
Stop replacing tiles due to freeze / thaw heave. Get rid of designs that guarantee trip hazards when edges curl or backing plates rise or ridge. VANGUARD products literally attach to every micron of the applied surface so water can’t get underneath allowing moisture to degrade the structural surface below. There are no screws or bolts to come loose, or rust.
Vanguard; Designed to succeed.
