Internal Column Reducers

Please fill out the form below and a member of our team will be in touch.

Slip inside a hollow pole, post or column, providing a reduced diameter spigot for lanterns or brackets. They are also less visible than external reducers, and incorporate a sealing gasket to prevent water ingress.

These are designed to reduce columns and sign posts to accept lanterns or brackets. They are particularly useful for post top lantern conversions or to adapt a sign post to carry an outreach bracket such as our Type 40 bracket for external illumination of signs.


  • Less obtrusive than the external reducers, being fitted with a secret M8 cap screw¬†
  • Galvanised to BS EN ISO 1461:2009
