Leica GPH1 Adapter for SECO Telescopic Prism Poles

This SECO 2090-10 Pole Adapter is to be used on SECO 5507 thru 5527 Quick Change Prism Poles to achieve a correct target height when using a Leica GPR111, GPR121, & GPH1 prisms.

These Seco prism poles are designed such that they require the distance between the center of the prism to the top of the prism pole to be 150mm. This adapter adds 50mm + 32mm to the prism height of 68mm to acheive this for Leica prism assemblies.
