TSH-64 is one newly developped spring hinges for bamboo eyewear, wood eyeglass,TR-90 eyeglass,plastic frames etc, which is suitable for any frames which has the welding problem,yet the springs action is required.

How to install TSH-64 onto frame:
The installing way of front part of TSH-64 is exactly same as TSH-10,
while for temple part, you need to make one "T" recess in the temples, then insert the hinge into the recess, screwing the screws on the end.

Unlike the TSH-10,the spring case is visible on the temples.

Pay attention the front oval piece touches against the hinge bottom,right ? So metal against metal,never fear the wood temples will get worn in use.
