The Steel Dog Snap-Coil™ Tie is a multipurpose Transition Tie for “job-built” plywood concrete forms. With a button head snap tie electronically welded to a ½”coil tie end, the Snap-Coil™ Tie gives the user the versatility using of threaded coil rod for one-sided forming, long ties, and other purposes, while still using familiar, low-labor-cost means of attachment to formwork (slotted wedges, Jahn brackets).

Snap-Coil™ Ties can be threaded back-to-back to create long- or unusual-length ties with different end configurations. For example, a 27½” tie with a long tail on one end and a short tail on the other can be easily assembled on-the-spot from standard components


Typical Applications • Battered walls • Mass pours • Pile caps • Pilasters
