The PLL 2 cross line laser from Bosch is the ideal tool for aligning lamps, shelves and pictures perfectly straight at the same height, parallel to one another or along a diagonal.

To do so, the precision tool projects absolutely straight vertical and horizontal laser lines. 

The automatic self-levelling function takes less than five seconds and works with a typical accuracy of ±0.5 mm/m. With the practical incline function, lines can be projected at any angle you require. 

The incline function of the PLL 2 from Bosch is useful when you want to hang pictures on the wall parallel to a roof slope or a staircase. 
The Bosch PLL 2 combines a cross line laser and a digital spirit level in one. When the PLL 2 is being used as a digital spirit level, a bubble vial appears on the left-hand side of the display. The corresponding incline is shown on the display with an accuracy of ±0.2°.

Benefits for you at a glance:

• Projection of a laser cross and individually switchable horizontal and vertical laser line
• Self-levelling function, which means absolutely straight lines
• Adjustable laser lines/laser cross for projecting lines at any angle you require
• Practical use as digital spirit level
• Large working range up to 10 m
• Easy and intuitive operation

Thanks to the precise positioning with the aid of the target, extremely high accuracy can be achieved. With the integrated 1/4" thread, the PLL 2 from Bosch fits on all conventional tripods and allows DIYers to keep their hands free to work on their job.
