Tent poles for the repair of broken or weakened poles, most tent manufacturer's use the same diameter poles but the pole diameters alter depending on the size of tent and how much the pole will need to flex and bend to fit the individual model of tent. Most poles will not fit your tent without some trimming of the pole to the required length so a little forward planning would be preferable to make the replacement easier to do on site.(An emergency short term quick fix can be done on fibreglass poles via the use of electrical tape bound tightly around the poles).
