This extremely versatile adjustable threshold ramp is supplied in two sections which are easily fitted together, with each section giving an additional 25mm (1\") raise over the previous section.This two-part version therefore, rises to a maximum height of 50mm (2\") and is supplied with a small lip with two holes that allow secure fixing to the threshold. The two lightweight sections slide together easily and are extremely simple to adjust and fit. The lower section can also be used on its own, in cases where a 25mm (1\") raise, is all that is needed.
