End Caps
Product Information
We now offer a wide variety of plastic end caps in several styles, finish and sizes. The rigid and semi-rigid end caps can be made to fit slightly smaller sizes than those specified in the "Inside Diameter" column with the use of weather stripping easily found in hardware stores (not included).
If the size you need is not listed in the table below, then we do not carry it.
To see photos of the various end cap types, please click on the "Zoom" button above.
Key for end cap Type:
* R = Rigid (
Stiff end caps typically use for telescope dewshields and larger binoculars
)
* SR = Semi-Rigid (
The most common type of semi-stiff end caps typically provided with eyepieces, finders, binoculars, etc.)
* F = Flexible (
After-market end caps commonly used for pipe fittings, but work very well for astronomy equipment too
)
