Telecom Clip
Mueller clips are the original clips. Our current designs reflect 95 years of continuous innovation and improvements. Our clips use springs made of the best materials, wound to the highest tolerances for strength and holding power. The combination of a strong spring and sharp teeth produces a clip that has true "bite and hold". The key to personal and equipment safety in using a clip is its insulator. Every Mueller clip manufactured has an insulator designed and formulated specifically for that clip. Many of our clips have exhibited a usable life of over 200,000 cycles and additional long term testing goes on continuously. We do this to ensure that our customers receive the best design and most reliable products that can be manufactured today. Mueller clips and insulators outlast all others and cost less because they last.
