This seal is a compacted rubber seal 3mm in thickness in a 15mt Roll with a 20mm width. It is typically used to re-seal 45 degree lights when they are ventilated or pressurised. The seal has a single side adhesive tape which can be fitted directly to the aluminium or steel glass frame before being re-fitted to the spray booth. This seal can also be used on inspection hatches to provide an air tight seal or on doorways.
