Those springs are a hoot! Be sure and use the little tool. A bit of advice from recent experience; I installed those guys on my trailer last year. Never had a problem with insects but wanted to avoid them. This year the wire mesh I installed over the furnace exhaust caused the high limit switch to activate repeatedly after it got hot. Seems unbelievable but just that small amount of restriction caused it to happen. Removed the screen and haven't had a minutes trouble since. We do have a 35k furnace so that may be part of the issue. Just a heads up.
