The OMER modular platform can be configured so many ways to solve special fastening needs. This type of tool is affectionately called a LONG MAGAZINE AUTOMATIC model. But it offers more than high SPEED alone. Precision made by Omer to provide a carefully planned and consistent rate of fire. The best cyclic rate can be "dialed in" to just the right velocity suited to each application need. For some applications it is nice to Drive Wide Open at top... speed but there are also requirements for a slower rate of fire. Plus, Omer's refined design dials up and STAYS set at the automatic speed desired. Kept instantly in reserve right at your finger tip, is the ability to OVER RIDE the automatic setting. This provides the option of careful single staple placement. The best of all worlds.
