Check the listing for details. * (Set of 3) Button Knobs & Ring Finger Flex * TruBall Releases - Goat HBC Abyss. Condition: New without tags. Listed at 20.00 USD. *** Release in picture is NOT included. Only shown as an example for fitment *** NOTE: Since truball has now included a newer style adjustment thumb post, I want to emphasize that this knobs will NOT fit that newer style post. Please see last picture of what that newer post looks like. You will be able to use these using the direct fit or to the older style teardrop extension. So if you do have the newer style post you won't be able to use these with it. Includes: 1) 5/8 inch thumb knob - centered hole 2) 3/4 inch thumb knob - offset hole 3) Ring finger extension - u can choose 1 flex attachment from the 7 available options 4) 1 set of 6-32 socket screw and hex nut * LEFT HAND - Due to limitations on the amount of options I can set, I was unable to have a left hand option. If you wanted to order left hand just put in order comments when ordering that you want left hand. Thumb Peg Knobs The larger 3/4" knob has a offset hole to allow you to set the position to your liking. The smaller 5/8" knob has no offset. Please see the 4th picture showing the attachment holes. You can choose between 3 peg styles in diamond Knurl, spiral Knurl or the gripper. Ring Finger Flex Extension The ring finger extension will fit truball releases that has the flex finger attachment option. Releases from truball are often named with FLEX in its product such as: Blade Pro Flex Fulkrum Flex Abyss Flex HBC Flex Goat But it will also fit the GOAT which doesn't have flex in its name. As long as your truball release has a detachable ring finger attachment then it can use this extension. The 5th picture shows how it would connect. I made these non-adjustable as I wanted the extension to always have a solid connection against he release body. For this reason the hole is made perfectly to attach it at the rest body. I give options for a low, medium and high. Angle Options There are 3 options for the flex angles: Low, a medium and high. Using the hash marks on the underside of the stock extension these are the conversions. Low - zero setting Medium - hash mark 5 High - hash mark 10 Texture Options The ring finger extension you can choose between a smooth finish or a knurled finish on the face of the extension for the 3 finger option. All 2 finger are the smooth finish. Color Options Color options are available. If you prefer other colors, please message me and I can send you pics of the exact color shade I have if I have it.
