The 1.5THT adapter holds a 1.5″ diameter SMR and may be mounted on a customer-supplied base unit using one of two different stud sizes, depending upon the model ordered. The bottom side of the 1.5THT contains an internal thread for securing this item to a base unit. Both available models (see table below) have a 5/8″−11 internal thread which fits surveyor’s tripods or other instrument adapters. However, the model 1.5THT-.25-20 is supplied with a locking threaded insert to allow the unit to be used with camera tripods or other mounts having a 1/4″−20 thread. A 1/4″ hole on the side is provided to assist in removal of the adapter if needed. The SMR seats on a 3-point conical land and is held in place by a nickel-plated Neodymium magnet.
