Ringside Heavy Duty Bag Spring by Ringside

Did not give the dimentions in description so when it came it was way bigger than I expected or wanted for boxing bag. About 13cm long and 4cm wide with super strong iron. My 20kg bag didn't even pull it away slightly. Will work well for extremely heavy bags or patio swings

I use this on a 100lbs heavy bag, the tension seems just right. I had to shorten the bag chain to account for the 6” length of the spring so my head punches land more in the middle of my bag. I like the simplicity of the hook, it makes hanging the bag by yourself very easy and hasn’t fallen off yet during a workout. The hook clearance is small, it won’t come off my ceiling hardware without the removal of a bolt, however the steel ring on my bag is narrow enough to pass over the hook very easily. I can see it flexing quite a lot, absorbing a lot of shock from the ceiling joist.

Ya tengo como 2 semanas con él y desde que lo puse se notó gran diferencia. Donde tengo el costal hay techo y una puerta de metal, y sonaba muy fuerte con cada golpe. Ahora el resorte absorbe el impacto y dejó de temblar todo. No se que tango dure, pero lo volvería a comprar.

Used it to secure my 120 lb Aqua Training Bag. The bag is installed as pictured, braced across three joists in our basement. Before, uppercuts horribly shook the house and all other punches were unpleasantly noisy. Installed this spring. Now you can still hear the heaviest punches, but zero vibration, all of it is absorbed by the spring. At same time, the bag doesn’t bounce or really respond differently then before. The perfect spring for the bag.
