The 250-06 Extra-Long Rail Clamp is 0.900" long, half-again as long as the standard 0.600" 250-01 Straight Rail Clamp.
250-06 is used anywhere that more length and/or strength of connection is required than is provided by the 250-01 clamp. Several clubs use it to connect individual members' display sections together to form larger layouts.
Each 250-06 clamps completely around the rail flange--top, bottom and edges--as well as the base of the rail web. This exclusive Hillman design results in a joint that is extremely strong in all 3 dimensions and that ensures conductivity.
