Barrel locks with return spring can be easily screwed onto doors, hatches and hoods. These locks are available in two different variants: bevelled upward or bevelled downward. The bevelled surface allows the application to be closed or opened without actuating the grip. The integrated return spring always brings the grip back to its original position. Type of operation: When the grip is pushed, the barrel moves into the open position and the door can be opened. When the door is pushed to, it is locked automatically by the bevel.

Ball lock pins are used for easy fastening or joining of components. The two balls are disengaged by pressing the push button and the pin can be slipped into holes in the workpieces. When the push button is released, the balls lock the connection securely. Shear force double shear (F) = S · τ aB max. The values given for the shear force are the theoretical breaking load. These are non-binding reference values without consideration of safety factors and exclude any liability. The values given are for information purposes only and do not constitute a legally binding assurance of properties. The load values have been calculated in accordance with DIN 50141. Each user must determine individually whether the ball lock pin is suitable for the respective application. Different materials in which the ball lock pins are used, weather conditions and wear can influence the determined values.
