Long springloaded turnbuckles by Torklift. Had them on my truck camper for barely a month before i sold the rig. Receipts available. Unblemished. No rust, or binding threads. Even the stickers are still on and looking new.
New, these sell for $180. Save $80 buying from me. I can ship fedex free anywhere in country
