About SimpleShot Premium Latex Tube If you want a band that just keeps going, this is it. Small-diameter tube latex is prized for how resilient it is, tough enough that tearing, nicking, or breaking one is hard to do, so the set you rig keeps shooting long and hard. It's snappy too, with a quick, lively retraction shooters love. Made in China to SimpleShot's spec, it comes in a few sizes so you can match it to your ammo, and you can run a single strand for lighter shots or double it into a loop for heavier ones. Reading the numbers. A tube's name is really two measurements, its inner diameter and its outer diameter, so 1745 is 1.7mm across the hole and 4.5mm across the tube. Bigger numbers mean a bigger tube; a bigger gap between them means a thicker wall and more power. That's why 1632 and 2040 run lighter, 1842 sits in the middle, and 1745 hits heavy. Sold by the 10 meters, there's plenty to build set after set. Rig it, shoot it, and shoot it some more.
