About this product
The Box Beam Spirit Level range is designed specifically for installers who require absolute precision when fitting UPVC, aluminium, or timber systems. For the glazing professional, a reliable level is the difference between a smooth-sliding patio door and a costly call-back. This set provides both a 900mm level for larger frame spans and a 400mm level for tight apertures and cill checks.
Constructed from a high-strength aluminium box section, these levels resist the warping and twisting often found in cheaper alternatives. The precision-milled surfaces ensure a flat contact area against frames and tracks, while the shock-absorbing rubber end caps protect the vials from the rigours of the building site.
Key Features:
- Glazing Trade Precision: Milled surfaces provide the flat contact needed for accurate window and door frame levelling.
- Heavy-Duty Box Section: Reinforced aluminium profile ensures the level stays straight and true, even after heavy site use.
- Vertical & Horizontal Vials: Features high-visibility vials for quick, accurate readings in every orientation.
- Shock-Proof Protection: Rubberised end caps absorb impact, protecting the calibration if the tool is dropped on-site.
- Ergonomic Handling: The 900mm model includes integrated hand grips, making it easier to hold steady against vertical frames.
