Whether you are right-handed or left-handed, the pump lever can be easily converted to suit your preference, providing an optimal working position. The length of the pump lever can also be adjusted if required.
Protected Internal Pump
The pump is securely located inside the container, protecting it from external damage during use, transport, and storage.
Integrated Spray Tube Holder
For convenience during work breaks, transport, or storage, an integrated holder keeps the spray tube securely in place, protecting the spray attachment.
Integrated Measuring Cup
The tank lid cleverly incorporates three measuring cups (10 ml, 20 ml, and 50 ml), allowing you to mix your spray agent accurately and conveniently directly on the tool.
Central Output Tube
The hose is attached centrally at the base of the tank. This design provides excellent freedom of movement and manoeuvrability for both right and left-handed users.
Comfortable Hanging Strap
The sprayer’s belt attachment is firmly fixed at the top, with two eyelets at the bottom for suspension. The back straps are fully adjustable, making it easy and comfortable to carry the tool on your back.
