SERIES GSLLinear Slot DiffuserEndFlangesand EndCapsEnd caps-Ref: ECEnd Flanges-Ref: EFFixingOptionsThe standard fixing option for the GSL slot diffuser is thepopular concealed bracket fixing. The concealed bracketsare fixed to the rear of the diffuser and quickly push fit intothe plenum. Unclipping the diffuser blade allows access tothe captive nuts on the brackets to tighten and align the unitin place.Where access is easily available to the ceiling void analternative fixing option is to simply drill through the neck ofthe diffuser and the plenum box and then rivet into place.This offers a unit cost saving over the standard concealedbracket fixing arrangement but may take a little more time toinstall.A further fixing option is offered in the form of a toggle latchclip. One of the quickest and easiest fixing options by far.The diffuser is simply located into the plenum and firmed upinto place by pushing the toggle fixings into place.For installations without a plenum the diffuser alwaysautomatically includes holes for standard drop rod supporton the diffuser back straps. The back straps are spaced onapprox. 300mm centres.StandardConcealedBracket FixingOptionalDrill and RivetFixingOptionalToggle FixingOptionalSupport Brackets(By others)BlankingPlatesFor inactive or dummy sections, matt black blanking platescan be supplied.
