Rod canisters can withstand temperatures of 225 deg F. Their rugged construction prevents electrodes from moisture and damage. Features include a belt clip for carrying and four separate dividers to keep electrodes organized on the job. K-T rod canisters will now have a new feature to keep the electrodes airtight. K-T rod canisters now have a threaded cap without a gasket. By overlapping the lid and threads the new style rod canisters are more airtight than ever. A second advantage to this new seal system on the rod guards is there is no gasket to dry out keeping a very consistent seal on the rod canister over longer periods of time.
