Installation of these clips is done on the back side of the joint and makes for VERY tight joints that really help to improve both the electrical connection - but also the smoothness of the joint - something that is really noticeable if you are running non-magnetic (old Aurora T-jets) or lower magnetic down force cars like AutoWorld X-Traction / Thunderjet cars. I found the biggest improvement and ease of use being to do a corner section and one piece of straight track in both directions from the corner. This keeps the clipped together sections reasonable in size, allowing for manageable flipping over after installing the clips. Great to see these tight fitting spring clips being available again!

Will help insure that the track will keep tight while fasening track to road bed
