In cases where the compressed spring needs to move in and out of a specific slot, a coiled spring compressor is usually the best device that helps remove the spring. The compressor compresses the spring and it makes it so the spring can be removed. Usually when both sides are compressed the spring will be able to be moved out.
Usually the coil spring compressor is referred to as the external coil spring compressor. External coil spring compressors are used for springs in cars, like the suspension springs or the shocks. These compressors are not sold by Coiling Technologies but may be found at a car service business.
