Internal stop ends blank off the end of a fitting such as a running outlet or gutter angle.  If you need to blank the end of a gutter you should use an external stop end.  The internal stopend is tapered to fit easily into fittings and has an overhang feature which reduces flex in the fitting.
 
Deepstyle is a semi elliptical system which offers more effective rainwater drainage on larger roof areas. This can reduce the number of downpipes required, providing cost savings and perhaps overall appearance improvements.  The system is characterised by an easy fix clip system, which facilitates simple installation whilst external fixing lugs allow easy access for cordless power tools.
 
The Deepstyle system utilises 68mm round downpipe and fittings. 
 
It is available in six colours including Anthracite Grey as well as Black, Grey, White, Brown and Arctic White.
