Chain-Link Top Rail End Cup 1-3/8 And 1-5/8
This is a single replacement rail end cup for chain-link fence. It uses a stepped bore that takes either a 1-5/8 in (41.3 mm OD) top rail in the 41.9 mm outer section or a 1-3/8 in (34.9 mm OD) rail in the 35.5 mm inner section. The 26 x 6 mm tongue has a 10 mm hole that fits a 5/16 in or 3/8 in carriage bolt and seats in a standard brace band, so you can fix one rusted or snapped cup without buying a 10-pack. Two 4.2 mm radial holes take a #8 screw to lock the rail in place. The cup is 48 mm across and 100 mm tall, and should be printed in PETG or ASA for outdoor use.
46-49 mm Chain-Link Brace Band
A clamp-on brace band for odd-size chain-link post pipe from 46 to 49 mm OD (1-7/8 in 47.6 mm pipe and 1-1/2 in 48.3 mm pipe), the sizes big-box stores don't stock. The 49 mm bore can tighten up to 8 mm around the post. A 9 mm cross-hole with a recessed square seat takes a standard 5/16 in carriage bolt to hold a rail-end cup or tension bar. The band is 25 mm tall with a 5 mm wall. Print it in PETG or ASA for outdoor use.
