Features

• High-Visibility Block Vials: Features 180-degree, 90-degree, and 45-degree shock-resistant bubble vials that remain highly visible under fluctuating light settings.
• Heavy Duty Aluminium Profile: Structural box-section build offers extreme strength and prevents deformation under jobsite pressure.
• Shock Absorbent End Caps: Toughened protective compound on both boundaries prevents damage or calibration drift due to structural impacts.
• Optimized Leveling Base: Machined base configuration ensures consistent contact with flat surfaces during essential horizontal or vertical measurements.
• Optional Magnetic Function: Offered with an optional integrated magnetic stripping surface to hold firmly against steel columns or piping setups.

Applications

• Masonry Layouts: Setting structural alignment during bricklaying, wall construction, and paving stones.
• Carpentry Installations: Verifying perfect plumb boundaries for wooden door frames, windows, custom cabinet partitions, and timber joists.
• Drywall Framing: Lining up interior partition studs and drop-ceiling grids evenly.
• Mechanical & Piping Works: Adjusting structural pipes, metal ducts, and electrical conduits using the multi-angle 45-degree or 90-degree configuration.
• Exterior Drainage Design: Establishing specific slope angles for concrete surface water runoff systems.

Usage

• Wipe down the landing zone to free it from plaster clumps, fine dust particles, or concrete debris before placing the tool.
• Position the lower face of the layout tool directly across the surface area you intend to balance.
• Look straight down onto the respective block vial to eliminate viewing errors from an angle.
• Move the underlying object or surface until the internal measuring bubble aligns squarely between the two benchmark line markers.
• To check vertical verticality, hold the side frame flat against the vertical post and monitor the 90-degree vertical vial structure.
