Max USA Our sister publication, Tools of the Trade, called the Superframer SN883RH the best of the best in its test of full round-head framing nailers. Superlatives include the lightest, the smallest, the most powerful, extremely well engineered, and the "king of ergonomics." It also has a patented anti-double-fire mechanism that lets you bump-fire or single fire without adjusting anything. This 3 1/4-inch nailer works very efficiently, countersinking nails into LVLs perfectly at only 100 psi. It features a last-nail-holding magnet to save nails and prevent jams, a self-cleaning filter, and extra-safe lockoff switch. 800.223.4293.
