UPGRADE GOAT & STRAYDOG JAMMER ARMS
Your jammer arms should not be trapped in one plane
Standard jammer arms are powerful but normally follow one fixed path. These dual-hinged adapters add multi-directional movement, then let you lock the angle when the exercise needs precision.
Central, 15-degree and 30-degree positions give you repeatable training angles.
Robust 5 mm construction for demanding jammer-arm training.
Genuine Oilite bushings support smooth, consistent movement under load.
Extends the jammer arm to increase reach and exercise versatility.
THE ONE-PLANE PROBLEM
Strong arms. More ways to use them.
Turn compatible GOAT and STRAYDOG jammer arms into a more adaptable training station for rows, presses and multi-plane lever-arm work.
Vertical movement only
Your lever arm follows the path permitted by its original hinge. Strong and useful—but restricted when the exercise needs a different line of pull.
Move freely or lock the angle
Use the dual-hinge system unlocked for multi-directional movement, or select a fixed position for a controlled and repeatable path.
BUILD THE SETUP YOU NEED
One adaptor or a matched pair
Choose the exact upgrade your installation needs. Then decide whether the matching one-inch detent locking pin or pins should be included.
SINGLE
Upgrade one jammer arm
Choose one adaptor for unilateral training, testing a setup, or upgrading one side of a compatible installation.
PAIR
Upgrade both jammer arms
Choose the pair for matched left-and-right movement across rows, presses and other two-arm lever work.
DETENT LOCKING PINS
Included or not included?
UNLOCK MORE TRAINING OPTIONS
Rows, presses and lever-arm work—without one fixed path
Unlocked movement gives the lever arm freedom to travel across multiple planes. Locking the adaptor creates a controlled path when repeatability matters.
Rows
Create a more natural line of pull for horizontal and diagonal lever-arm rowing patterns.
Presses
Set a controlled fixed angle or let the arm track more freely through compatible pressing movements.
Multi-plane work
Unlock the dual hinge for diagonal, rotational and other dynamic strength patterns.
BUILT FOR SERIOUS LEVER-ARM WORK
