Ronstan Sealoc turnbuckles have a sleek, low-windage profile with no sharp edges. Ronstan Sealocs are easy to adjust and are lighter than conventional turnbuckles
To adjust just turn the coupling nut, which is free to rotate on the turnbuckle barrel, and is secured with a quick turn on the cone shaped locking nut. A sight hole in the coupling nut enables you to verify adequate thread engagement.
Ronstan's turnbuckles are made with grade 316 stainless steel bodies and terminals with chrome plated aluminum silicon bronze coupling nuts and chrome plated SMH brass locking nuts. The compatible but dissimilar metals for the threaded components eliminates thread seizure.
This turnbuckle swages to a 5/32 in (4mm) wire and has a minimum length of 8 1/8 in (206mm) and a maximum length of 10 11/16 in. (271mm). The toggle requires a 5/16 in. (8mm) pin diameter.
