Question:
What size is the low profile zerk grease fitting? When the trailer hitch side was welded, the fitting was ruined. Too much heat froze the ball bearing and one cannot grease.

I spoke to Lock N Roll and they use 6mm x 1 low profile zerk fittings in their Articulating Coupler # 336TS504. The low profile ones can be a little difficult to locate, but they are out there.
We do have the Marlboro Replacement Brass Grease Zerk - 6 mm x 1.00 STD # MA35ZR that can technically be used, but it is a standard fitting and not a low profile.
