Ordered wrong size my fault did not use or return.

You said that you ordered the wrong part. I want to make sure that you had purchased this for the following tow bars: Falcon 2 Falcon All-Terrain Blackhawk All-Terrain The dimensions of this cap are 1.375 inches x 1.375 inches x 0.75 inches. If you can let me know which tow bar you have, I might be able to find you an end cap.

The plug is hard plastic. I would rather it was hard rubber that would be more pliable and would maybe be easier to install. But by using a plastic mallet and an extension, I was able to hammer it in place. It fits well and seems to seal.


This should not be a one time use item. I wish these were made of rubber so that when I follow the procedure for cleaning and maintenence I did not have to replace each time.


The product is exactly what I needed. Etrailer was quick... had it in just a couple of days!


These products are very poor in design. They should be rubber. Plastic just crack and break in the cold.


excellent service, got the replacements very fast.


Good to get a hard to find part

A perfect fit that’s working perfectly

  • How To Clean Tow Bar Arms On Roadmaster Tow Bar

Then, you will want to move the arms in and out and rinse off with water. After rinsing the arms, you will want to dry the arms thoroughly and finally spray a dry silicone spray on the arms.
