Interfast is an adapter designed to connect the Toolbag and the Tooleash connection loop to the work harness. It is universal and compatible with any harness that has belt slots. The design of the adapter is durable and compact to reduce bulk on the harness and keep all attached elements safe when working at height. The top clip allows for quick attachment of the Toolbag, the Fast button allows for quick and easy disconnection, and the bottom eyelet allows for the attachment of the Tooleash loop. The load capacity of the upper clip is 6 kg and the lower eye is 5 kg.
