Differences between Programa Plus and Classic

• The sleeve is thicker, threads all around, "without breaking points".
- Minimizes the risk of the sleeve cracking in case of overload.
• The threads run in a full circle around the sleeve, which creates a better grip in the frame. 
- Prevents over-tightening of the threads.
• The sleeve has 4 sharp fiber cutters that cut through the fibers in the frame. 
- Leaves a nicer cut hole and reduces cracking on the edge of the hole. 
• A fiber cutting groove has been added to the end of the screw.
- Reduces the risk of cracks when the screw is screwed close to the post edge.
