Strictly Ceilings PRO-SERIES ONE-PULL Pop Riveter, designed by our suspended ceiling installers to install rivets in a single pull when used with Strictly Ceilings 1/8" Pop Rivets. The one-pull system eliminates fatigue associated with other pop riveters that require multiple pulls to install pop rivets. The PRO SERIES Pop Riveter also features a hardened steel jaw set, a heavy duty, professional-grade body with non-slip handle grips and (4) different diameter interchangeable nose pieces. Smooth, easy, one-handed operation and a spring-loaded handle for automatic ejection of mandrel, makes this tool a must for the professional ceiling installer!
