The PARKS OPTICAL Spider for 19" OD 18-1/2" ID Telescope tubed is a sturdy metal secondary mirror holder for Newtonian telescopes. Included is hardware to attach the spider to your telescope. A nut on the inside of the tube and the outside of the tube securely fasten the spider to the telescope tube. In the center is a 3/8" ID through hole for mounting the secondary holder to the spider. The vanes are pined and bolted to the center piece to insure that there will be no movement. The spider is powder coated black to reduce any light reflections.
