Every finger, its share.
Made to your fingers. Kind to your pulleys.
Your fingers are not the same length, so why train on a straight edge? Enter how much longer your ring, middle and index finger are than your pinky, and how wide each finger is. Tailr Edge shapes each edge to match, shows you the result in 3D and gives you an STL to print or a STEP file to edit.
- Made to measure: 3D-printed from your finger lengths
- Even load: all 4 fingers loaded evenly, including your little finger
- Open drag position: middle joint extended, minimal load on A2
- No pressure points: so no skin problems on your little finger
- Same position every time: consistent, measurable training
All values in mm. Total width: 79 mm

Even load. Every finger. Every session.
On a straight edge your longest fingers do most of the work while the others hang along. Tailr Edge gives every finger its own edge at its own length, so all four fingers grip the way your hand is built.
Made to measure
Each edge is 3D-printed from your own finger lengths and sits exactly where that fingertip lands, so your hand stays in a natural position instead of bending to fit a straight line.
Even load on all 4 fingers
Every finger carries its own share, including your little finger. No single finger takes the peak load while the others barely touch the edge.
No pressure points
The load is spread across the skin too, so you don't get pressure points or skin problems on your little finger.
Open drag position, kind to your A2
The middle joint stays extended, which puts minimal load on the A2 pulley. Train hard without worrying about it.
The same position every time
Your hand lands in the same spot every session, so your training is consistent and measurable.
Carries over to real holds
Every finger is trained to its own maximum, which translates much better to three-finger drags and two-finger pocket holds.
Measure your hand in 4 steps
Trace your hand
You only need to measure one hand: the other is usually the same. Lay it flat on a sheet of paper, fingers relaxed and together, as you would hold an edge, and trace around the fingertips with a pencil held vertically.
Measure the lengths
Draw a line through the tip of your pinky, square to your fingers. That line is 0. Measure how far the ring, middle and index fingertips stick out past it, in millimetres.
Measure the widths
Measure each finger across its last joint, where the fingertip is widest, with a ruler held flat over the finger. Do this for all four fingers. If the fingers feel cramped side by side on the edge, add 1–2 mm to each.
Enter your numbers
Type the three length differences and the four widths in the designer above. With the lock closed, both hands get the same values; open it if your hands differ and enter each hand separately. The 3D view updates as you type.
Each length is the distance between the pinky edge and that finger's edge, measured square to the 5° edge face. The original Tailr Edge uses 23.9 / 27.9 / 12 mm (ring / middle / index) and edge widths of 20 / 21 / 20 / 18 mm (index / middle / ring / pinky).
Everything except the edge positions and widths: the 17 mm front lip, the 5 mm and 3 mm fillets on every edge, the cord channel, the load hole and the mounting eyelets. If an edge gets too close, the load hole shrinks around its centre.
A printed part can fail without warning. Never hang more than you can control, keep your feet close to the ground the first time, and replace the print as soon as you see layer cracks.
