Question:
Hi, I have a question about your 21k lbs straight tongue couplers. Demco Channel Tongue Trailer Coupler - Silver - 2-5/16 Ball - 3 Channel - Bolt On - 21K Item # DM16080-52 What is the height of the channel of this unit? I see the other 21k lb option is from Titan and there is measurement of 3.75 ID channel height. Also what is the from the 5/8 mounting holes to the center of hitch ball? And what is the distance between the ball center and the front 5/8 mounting hole? It looks like this one comes forward further than the Titan version. Would be helpful to know this distance on the Titan also. Thank you

The channel of the Demco 21K # DM16080-52 coupler is 3 inches deep. The distance from the center of where the trailer ball would sit to the first 5/8 inch hole is 7 inches, and 12 inches to the second hole.
The Titan # T4853100 dimensions are a little different. The inside depth is 3-1/2 inches. The distance from the center of where the trailer ball would sit to the first 5/8 inch hole is 7-1/2 inches and 12-1/4 inches.
I've shown these dimensions in the provided photo.
