Alright I did a search and came up with these:
The first is a Cable Clamp,

Here's the thread I found on Th*nd3rs Pl@ce:

What he said he did is get some tape or some Thera and wrap it around the two sides of the clamp.
"The large clamps have a range of about 2 x 1.75" down to about 1 x 1.5". This opening is too large to create the desired tension so I wrapped each side with
theraband until the opening was down to 0.5 x 1.25".
The result is a VERY easy to use clamp that has the benefit of a quick release AND applies most of the pressure to the sides therefore being safer for the nerve along the top of the shaft and the urethra.
I simply clamp it over a partial erection and masturbate to a full erection, that becomes engorged and I push the clamp down to the base creating the desired effect. Very easy. Should be safer than circle clamp type ULI's and have the quick disconnect as even safer. "
The second is a multi clamp,

I'm thinking about getting one (if not both) of the above for when I start my girth work. Also I would be clamping it off fully starting at 1 minute, for oooh.. 10 sets. Every week or so I would increase the time.
Just gotta get this length and I'll be set!!
