The XE25S2 Channel Insert is designed for use as a dust cover, panel holder, or to route cables in XE series rail channels. When inserted with the flat side facing out, the extruded plastic profile covers the T-slot in the rail channel, preventing dust and dirt build up for clean applications. In this orientation, it can also be used to route cables and wires with up to 4.5 mm diameter. It can also be reversed as shown above to act as a panel holder within the T-slot for panels 2 to 3.2 mm thick. The insert is flexible and can be easily cut with scissors or a blade.

I had 4 25mm Rails in a square, with 1 TB4 uncut, used as a lid for a system, when moved, the TB4 was loose inside the rails so I wanted to use the XE25S2 in the rails to hold it steady. unfortunately I did not fit (tried sliding it, fitting the insert on the panel, fitting the panel on the insert inside a rail) together with the TB4 and I had to cut in half (along the length) of the XE25S2 to use as a small insert.

Response from Charles at Thorlabs: Thank you for your feedback. The XE25S2 insert is to suit panels 2.0-3.2 mm thick while TB4 is 4.76 mm thick. If fully inserted into the insert this may be a little thick to ensure a smooth fit.
