The Rocket Portal are an evolution of the original Salbany and Fig8 entrances aimed at thick and/or twin wall hives. Each baffle comes with a 60-65mm oak tube to provide passage through insulation such as wood chippings or cork.
They are sustainably hand made using either locally sourced timber or offcuts from a trusted local timber supplier. Typical woods include: Oak, Beech, Ash, Iroko and Sapele and, of course, Cedar.
Sold with stainless screws. We would recommend the hole into the hive is 25mm (1in). For more advice on installation check out our information page.
