Contents: GUNPRIMER (gunprimer) joint guard (joint reinforcement tape) Size: About 105x175mm Number of publications: 1,054 Tape color: Light gray Material: Polypropylene (tape surface non-slip coating) This is a special reinforcing tape to recover the looseness of joints and moving parts of the mechanical model. In order to reinforce a loose joint until now, it was necessary to adjust it by sharpening with an adhesive and then adjusting it by scraping or re-placing it, or by sticking it to the joint while cutting out a small tape by yourself. This joint guard has been developed so that even these loose joint parts can be easily maintained for a long time. Reinforcing tape has been cut into strips in six sizes to suit various shafts. In addition, it is a soft special tape with a non-slip coating on the surface, so it can reinforce the joints without applying excessive tension to the parts.
