As an exclusive partner with Gripple®, Western Excelsior offers the Gripple® Twist pins in four variants. The Gripple® twist pin is an innovative fastener providing significantly greater pullout resistance than typical straight pins or staples. The greater pullout improves performance in soft or sandy soils, allows for better tie down of seams, simple simulated checktrench construction and replacement of more costly hardware in some instances. Using a hand drill and specialized chuck, installing the fasteners is quick and easy. Galvanized for long life, and more durable than hand driven fasteners, Gripple® twist pins are more reliable and provide greater confidence in blanket or TRM tie down.
Gripple® twist pins come in two variants, each with two configurations. The TA1 is designed for loose soils and the TA2 is optimized for hard soils. TA1 and TA2 are both available in eight inch and twelve-inch lengths.
Gripple® twist pins can be used in conjunction with just about any RECP, however, are ideally suited to TRM tie-down. The large-diameter head gives ample catch without the need for additional washers. In comparison to other tie-down fasteners, Gripple® twist pins provide up to ten times the pullout resistance of other fasteners. Typically, a minimum of 25 to 50 pounds of pullout resistance is required for a TRM installation. In some soils, staples or straight pins may only provide 10 to 15. Gripple® twist pins make these projects viable with greater than sufficient pullout in poor soils.
Additionally, Gripple® twist pins are galvanized to extend the life of the fasteners when in-place. This can significantly increase the performance envelope of any TRM system, especially in conditions where vegetation is slow to establish.
Gripple® twist pins install using a cordless hand drill and unique chuck. The chuck is available with an extension to make installation even easier. Considering placement, hammer effort, and breakage, the Gripple® twist pins are more convenient and efficient to install.
Quick and easy, Gripple® twist pins are the ideal choice to provide a secure installation and save time on the job site.
