The Edge Grip™ FWH1G is a unique eight-position, clear edge filter wheel. Its new Edge Grip filter mounting design makes it stand out from other filter wheels. While typical filter wheels employ cumbersome retaining rings to hold the filters, the FWH1's clip mounting design allows fast, tool-free installation / removal. The unique clip design has the added benefit of giving clear edge access to the filters it holds. Additionally, it can hold up to eight filters instead of just six. The FWH1G has two threaded holes (one 8-32 and one M4) in its body for post mounting. The FWH1G has a filter guard incorporated into the design which is removable.
