1. Dimensions:	Vigil Antislip Stair Nosings are measured in three dimensions: width of step (A); depth of step (B); and return (C).
A:	Width of Step: Because steps vary in width from area to area. Vigil Antislip Stair Nosings increase in width from 450mm to 1200mm in standard 150mm increments. Personnel rarely walk on the very sides of steps, so it is recommended that Stair Nosings 150mm - 300mm narrower than the overall step width are ordered. This leaves 75mm - 150mm bare on each side of the step, hence saving the customer money and allowing visual inspection of the step.
B:	Depth of Step: Most accidents occur on stairways when personnel slip on the leading edge. Up to 80mm from this edge is the most important area to be protected by Vigil Antislip Stair Nosings. Different areas, however, have different requirements so Vigil Antislip Stair Nosings increase in depth from 80mm to 220mm in 50mm increments. For most situations a "B" measurement of 80mm is recommended.
C:	Return: The return dimension is a standard 20mm and exists for 3 reasons; to offer visibility whilst ascending steps, to give the Stair Nosing added rigidity, and to offer non-slip protection right around the leading edge.

D:	Leading Edge: Vigil Antislip offer a right angled Stair Nosing to go over grating and a Bullnose Stair Nosing, for installation over curved chequerplate steps. The 8mm radius offers a larger surface area of contact between the surface and the sole but can only be installed over existing bullnose steps. Standard Dimensions: A: 450mm (17.7"), 600mm (23.6"), 750mm (29.5"), 900mm (35.4"), 1200mm (47.2") B: 80mm (3.15"), 130mm (5.12"), 180mm (7.10"), 220mm (8.70") C: 20mm (0.8")
2. Grade:	Three standard grades exist in the range of Vigil Antislip Stair Nosings: Commercial, Industrial and Offshore. Commercial grade is normally used in internal areas where heavy spillage and soilage does not exist. Industrial grade is used in most external areas where there may be spillage and/or soilage of lubricants. Offshore grade is used in areas where there is a high build up of grease or oil. This surface is the most severe and is not affected by very heavy spillage and soilage of chemicals or lubricants.
3. Colour:	In all Industrial or Offshore applications, the Safety Yellow color is recommended. If Commercial grade Stair Nosings are to be utilise internally, other colours which are more aesthetic may be preferred.
4. Foundation:	1.2mm Colorbond steel is normally used as the foundation for Vigil Antislip Stair Nosings. This patented product offers excellent resistance to corrosion under most circumstances. If Stair Nosings are to be used in splash zones, we recommend 1.2mm marine grade stainless be used as a foundation. Electrolysis must be considered though if it is being installed on galvanised steel.
5. Installation:	If Vigil Antislip Stair Nosings are to be installed over plain steel grating, universal saddle assemblies are used. These fit all sizes of grating and consist of a galvanised saddle, galvanised pan head metal thread and a nickel coated Nyloc locking nut. Stainless steel saddle assemblies are also available for splash zones. The stainless steel saddle itself is threaded to facilitate installation and reduce the risk of dropping fasteners through the grating. Holes must first be drilled in the Stair Nosing from the back lo the surface, in between grating load bars and approximately 50mm in from each end. If accurate measurements are given all Stair Nosings can be predrilled during manufacture. Installation over chequerplate is more straight forward and does not require predrilling. Series 500 wafer head Tek screws are used and will drill through Vigil Antislip and up to 10mm chequerplate before self tapping and fastening.
6. No. of Fasteners:	The following Stair Nosings require two fasteners per piece. 450mm x 80mm x 20mm 450mm x 130mm x 20mm 600mm x 80mm x 20mm 600mm x 130mm x 20mm 750mm x 80mm x 20mm 750mm x 130mm x 20mm The following Stair Nosings require 3 fasteners per piece. 900mm x 80mm x 20mm 900mm x 130mm x 20mm 1200mm x 80mm x 20mm 1200mmx130mm x 20mm The following Stair Nosings require 4 fasteners per piece. 450mm x 180mm x 20mm 450mm x 220mm x 20mm 600mm x 180mm x 20mm 600mm x 220mm x 20mm 750mm x 180mm x 20mm 750mm x 220mm x 20mm The following Stair Nosings require 6 fasteners per piece. 900mm x 180mm x 20mm 900mm x 220mm x 20mm 1200mm x 180mm x 20mm 1200mm x 220mm x 20mm
7. Cleaning:	Because of the extreme hardness and chemical resistance of Vigil Antislip, cleaning can be effected with high pressure steam or water, degreasers, detergents or solvents. Stubborn soilage can be removed with a stiff deck broom. If solvents have been used, hose off with water at your earliest convenience. Do not use scrapers or wire brushes.
8. General:	Never install Stair Nosings on only a portion of a stairway, as a change of conditions is more dangerous than overall poor conditions. Ensure that Stair Nosings are installed correctly as loose Stair, Nosings can be dangerous. If using electric or pneumatic tools to install, ensure that appropriate safety glasses and ear protection are worn.
