The Flexible Alternative

Need a plug that is more pliable? For greater flexibility, consider our line of vinyl Plus Plugs as alternatives.

Made from a flexible vinyl material, these plugs provide a secure fit.
Vinyl material adapts as it is placed into a hole – as pressure from the insertion process is released, the flexible vinyl material expands inside securing a tight fit.
Vinyl Plus Plugs are easy to install and do not crack, split, or shred over time.
