Established in 2013 the DETA TTE brand is an amalgamation of two market leading companies Top Tubes Electrical and Stephen Glover, both highly recognised British suppliers of conduit tube and accessories with over 50 years’ experience in supplying the UK and export markets.

The quality of the DETA TTE conduit tube and accessories remains unrivalled in the industry and this is recognised by the highest levels of specification and major project installations worldwide.

With a comprehensive range and significant stocks held in two central distribution depots, DETA TTE covers the needs of every cable management installation.

DETA TTE Conduit Tube

DETA TTE steel conduit tube is suitable for use in the most demanding environments. It exceeds the maximum “very heavy” strength classification and can easily be formed on site.

Deta TTE conduit is hot dipped galvanised after manufacture to comply with Class 4, offering heavy protection inside and out. Galvanising is undertaken on a purpose made plant to ensure an even coating and employs a final superheated steam blast to ensure the bore is smooth and clear of defects which might damage cable installation.

BS EN 61386 compliant Class 4 Conduit is available in 20mm and 25mm external diameters in 3metre or 3.75metre lengths.

BS 4568 compliant Class 4 Conduit is available in 20mm, 25mm and 32mm external diameters in 3.75metre lengths.

Deta TTE Conduit Tube is threaded at both ends and is supplied complete with a coupler and one plastic thread protector cap.
