If the radius of curvature on the tent tubes (measured in an erected tent) is smaller than the following limits or tolerances, prebending of the tent tubes is required. Prebending removes the excess stress put on the tubes and brings the stress below the maximum allowable level. Prebends are calculated and measured (in inches) as the offset of the tube forms a straight line. Tubes with prebends form a constant arc, with approximately 1.5-2 inches at each end of the tube remaining straight to allow the inserts to function smoothly.
As part of Easton’s customer service, we will determine the prebend parameters for your specific tent model upon request. You may send your tent to Easton for this complimentary stress analysis. For details contact Easton at 800-800-6686. Note: prebends are only available with full radius bends.
