Turnbuckle

Boost form‑setting efficiency with our rugged Unicon Turnbuckles.  A 1‑inch, self‑cleaning coil thread inside the turnbuckle lets you set or release tension in seconds. The unit telescopes from 37 in. to 40 in., giving you a precise 3‑inch adjustment window to square walls or columns on the fly. One end carries a formed nailing plate with pre‑punched nail slots plus a 15/16‑inch opening that accepts standard ¾‑ or 7/8‑inch steel stakes for secure anchoring. Heavy‑gauge steel construction stands up to repeated pours, delivering long service life and lower labour costs. Safe working capacity ultimately depends on the quality of the lumber and the nailing or staking method used.
