Etiflex Patented Periodic Inspection tags are used to record periodic inspections that are greater than 90 days apart. The Standard Tags will work for most items that are stationary or mounted like a fire extinguisher on a vehicle.  The heavy duty tags are for items that get moved around and used in the field like lifting slings and gear. The heavy duty Tags are made with the same material and specifications as the standard tags and then include embedded fibers that give it increased tear resistance.
 
The Kits include 100 tags and a Heavy Duty Punch and leather holster.  If you need more tags you can also purchase refills in bags of 100 tags.
