	A half metre gauge which is ideal for measuring defects in the footway.

	An extending gauge which operates as a standard one metre gauge, but can be quickly and easily extended to span two metres. It consists of an adapted one metre gauge plus a second metre scale beam, a joining beam and four large fixing screws. The datum slider will move along the full two metre length.


	When the gauge is packed away the fixing screws are "parked" on the joining beam and it all fits into the one metre case.
	NEW Following the success of the Extending Gauge which spans up to two metres we now produce a HALF METRE GAUGE WHICH EXTENDS TO ONE METRE AND IS SUPPLIED IN A HALF METRE CASE MAKING IT VERY EASY TO CARRY AROUND

	The Invicta Highway Defect Gauge was developed in conjunction with Kent County Council Highways and Transportation Department and is now in use throughout the United Kingdom. It was devised as a dual purpose gauge:
	To provide a quick and easy method of checking the performance requirements of reinstatements for the New Roads and Street Works Act. To enable photographic evidence of carriageway and footway defects to be recorded easily and clearly. Both the horizontal and vertical beams of the scale are manufactured from 38mm x 6mm aluminium alloy, and the scales are reverse screen printed onto a tough polycarbonate strip which is inset into the beams. The scales are resistant to scratching and other accidental damage. The vertical beam is printed on both sides. The New Roads and Street Works Act scale is presented in one millimetre increments and for easy reference the reinstatement widths and intervention limits are all shown. The second side of the vertical beam is printed to a scale of 10mm intervals and will record a maximum depression of 200mm.

	Scales can be printed incorporating the name and logo of the Highways Department, District Authority, Public Utility Company etc. on the left hand side of the horizontal scale.

	The gauge is supported on three points, two of them on a swivel foot turning at right angles to the beam to provide stability. The sliders for both the feet and the vertical beam are spring loaded and can be used in any position along the beam. The positions of the sliders are interchangeable, making it easy to cantilever the vertical beam to measure kerb height, channel depth or edge depressions.

	For photographic purposes a plastic script board is available as an optional extra to enable the location and date to be recorded using a dry marker pen.

	When the gauge is stored the vertical beam is housed in the back of either of the foot sliders. A heavy duty plastic carrying case is supplied.
