What is Primpact ­>


Another exclusive feature is the 550A’s articulated, dual action and fully adjustable base which enables it to deal with an infinite variety of solid / engineered flooring from 3/8″ to 3/4″ (10 to 19mm).

Once set on the board, the front rollers rests firmly against the front edge of the board to keep the tool in position and prevent damaging the top finish.

The cam operated base plate adjuster maintains a consistent angle of penetration to deliver the fastener snugly into the nail pocket of the board with controlled penetration and perfect accuracy.

The compact base makes for a narrower racking gap and contributes stability.
