Abacus Lighting
Our two mid range masts - otherwise known as the HL250 and HL330 - are made with octagonal shafts and a gravity-lock mechanism, ensuring the mast is securely positioned before it’s lowered to ground level for maintenance. Cable glands mounted in the base also ensure a secure, watertight fit.

Technical data for columns & masts
The performance data for columns and masts gives their basic technical attributes only. The technical performance of a column or mast will be affected by local site conditions (terrain type, distance to sea, site altitude, windspeed) and the headload being carried.

Please Contact the Abacus Technical team to confirm the suitability of a column or mast for your application.
