Made for speed and accuracy, the RIDGID 3.5-inch Round-Head Framing Nailer fires at a rate of eight nails per second. Designed with a magnesium metal housing, the nailer is lightweight and durable. The tool-free selectable trigger lets you choose between sequential and contact firing modes. The rear-loading magazine offers a fast two-step reloading process. The dry-fire lockout system prevents accidental misfires, which extends the natural life of the nailer. The exhaust diffuser directs exhaust away from your face or body.
