William Optics Tube clamps 90mm (4697)

These 90mm mounting rings are constructed from solid aluminium and feature a powder-coated finish. The interior is lined with felt, making them compatible with most tubes of similar outer diameter and all William Optics 80mm telescopes, including all Megrez 80 and Zenith Star 80 models.

This is a valuable accessory for anyone looking to maximize the performance and versatility of their telescope mount.

• Each clamp includes five threaded holes: imperial 1/4x20 external threads and internal M6 metric threads, making them suitable for most dovetail plates, including those from William Optics.

• The clamps are equipped with user-friendly knurled knobs that feature Teflon paint protection at the ends.

• The felt lining offers additional protection, even for telescopes with delicate paint finishes.
