The H-Tube is our other rectangle storage tube and measures 1 1/8 by 1 3/4" with an adjustable length of 5" when closed and about 8" when extended. This tube may be more of an interest to our locksmiths who would like to hang the tube instead of putting it in a drawer or table top. This offering is for a group of 5 tubes in this size. When we started packaging products, we wanted to use a container that was more useful than a tiny cardboard box. Something was needed that would serve its purpose protecting the product that we made for you, but could also be adopted for further use. I think we must have done well in our selection because we have received so many requests from locksmiths that love these semi-transparent containers that we now make these slip over tubes available to you.
