The 1311 Series baton is made of 6061 aircraft grade aluminum tubing that will not bend, warp or break, even when exposed to extreme hot or cold temperatures. The finish is black anodize providing a durable high-quality finish that is corrosion and abrasion resistant. The aluminum tubing is filled with a wood dowel to protect the user’s hand from impact vibration and shock. The end caps are smooth and permanently pressed into place to avoid unnecessary injury.The “short end” of the baton is also used as a second handle. Rubber sleeves or grips may be added to improve the grip on the short end of the baton. The aluminum batons can also be knurled to improve grip. This model features a plastic handle that is injection molded around an aluminum insert. The aluminum insert is threaded on one end and contoured to properly fit against the body of the baton. Standard 5/16 x 2 inch Allen screw is used to assemble the handle to the baton. This handle assembly will remain tight against the baton and can be easily removed if it becomes necessary using the standard hex Allen wrench furnished with each baton.
