Advantages

• Enclosing flap provides protection against soiling.
• When using the spring-loaded flap lid, the flat external seal can be omitted (flap lid has sealing lips).
• The spring-loaded, enclosing flap falls back into the closed position at any time after operation and thus reliably protects against dust and water.
• Retrofittable for quarter-turns with insert and cylinder quarter-turns.
• For head diameter max. 32mm and head height 6mm.
• 180° Opening angle.
• Integrated stop protects the quarter-turn surface from damages.
