End clamps provide effi cient locking of sets of terminal blocks or other devices thanks to the screw or no-screw mounting on a TH rail. According to the type, they are designed to be used for TH 35 or TH 15 rails, as well as for all terminals in our range. For larger terminals (such as RSA 35 A and RSA 70 A), we recommend to use the RSA L 35-2 end clamp. End clamps are made of PA 6 polyamide, V0 flammability acc. to UL 94.
