<p>Trough has smooth inner surface, and base-mounted hook-on mechanism of resilient palte material, which includes hook (11) and resilient lip (10), enabling the trough to be secured to the floor grating with one simple manual operation. Contact lips prevent the mechanism from jamming underneath floor grating. Between two grating bars (1,2) fit two identical sections (3,4) fixed to base (5) of fodder trough (6). Base (5) is slightly recessed. Trough top rim (8) has enlarged diameter, whilse top rim (9) is curved inwards. Hook (11) and resilient lip (10) are curved to prevent damage to grating bars.</p> |
