Agena offers the largest selection of after-market end caps and dust plugs in the astronomy industry. Available in dozens of sizes and in a choice of materials and colors, we just might have that hard-to-find end cap to replace the one you lost (or never had) for your eyepieces, binoculars, accessories, etc.
Black plastic cap. Sold individually.
Useful Resources
A = 72.4mm / 2.85"
B = 76.5mm / 3.01"
C = 14.9mm / 0.59"
D = 73.2mm / 2.88"
Internal Ridges = Yes
Imprint inside cap = "73"
Notes:
(1) Some, but not all, end caps have 6-8 ridges on the inside rim. If these are present, the end cap size (A) is measured between diametrically opposite ridges as this will be the smallest internal dimension.
(2) If no ridges are present, (D) will be the same as (A). If ridges are present, (D) is typically 0.5-1mm larger than (A).
(3) The inside depth of the end cap is typically 1-2mm smaller than dimension (C).
(4) Dimensions (B) and (C) are subject to change without notice.
(5) Please note that it is rather common for many of these end caps to have light scratches or scuff marks from bundling with other caps, especially on the inside and on the larger sizes.
