This Seco Cradle features a lock on the bottom to securely attach your Juniper Mesa and Topcon Tesla data collector to a 1.25 inch diameter pole. With its pressure limiting design, it locks up the cradle when tight without risk of damaging the field controller. Constructed with corrosion-resistant anodized aluminum, this Seco cradle also includes stainless steel clamp screws with non-jamming coarse threads for easy opening and closing.
