Ear Guards :

Certified by All India Institute of Speech & Hearing, Mysore : All four sizes of earplugs satisfy the Sound Attenuation requirements as specified in the Indian Standard IS : 9167-1979 (reaffirmed 2002)

earplugs






  1. EAR-GUARDS are available in four sizes : Small, Medium-1, Medium-2 and large to suit individual ear canals. Choose correct size which snug fits comfortably to enhance effectiveness of attenuation of sound. Insert the spherical ends in the ears with light finger pressure and lateral movement.
  2. Material used : Nylon-6 is inert, non-toxic engineering plastic and retains high gloss, shape and cleanliness. No effect of body oil, ear wax. Can be wiped off clean with cloth and can be sterlized in hot water.
  3. Smooth, polished, spherical shape at the insert end ensures perfect seal with ear canel without straining ear muscles. Provide high wearing comfort, thus improve acceptance and willingness to use. remain clean and have very long life.
  4. EAR-GUARDS attenuate harmful sounds at higher frequencies to safer levels. Attenuation is much less in low frequency sounds so that speech and discrimination (SD) of warning signals can be perceived.
  5. EAR-GUARDS leave virtually the entire outer ear exposed increasing localisation accuracy of origin of sounds as compared to ear-muffs.
  6. For those with normal hearing , EAR-GUARDS will provide improved communication when sound levels are greater than about 85 dBs. Proper use of HPDs will prevent persons from developing a temporary hearing loss and allow existing temporary losses to recover before they become permanent.
  7. Prevent noise-induced hearing loss, improve general employee health, productivity and safety.
  8. Useful in factories, textile mills, power looms, hand looms, rock drilling, stone cutting sights, mines, traffic noise both road and railways, rock music, shooters and in airplanes. Usefule for light sleepers, students, meditation, avoiding snoring sound, swimmers and in hospitals.

Terminal Box / Junction Box in Nylon-6 for Electric Motors :
Quality Metal Works is manufacturing five sizes of Terminal Box in Nylon-6. The material used is Nylon-6.

Consistent Quality, Reliability of supplies, high visual appeal in glossy black color with pleasing functional design have increased our satisfied customers. Many motor manufacturers in India are using our Terminal Box ever since we introduced them ten years back. They are moulded under controlled conditions and expert supervision.

Assembly is two piece construction for fixing with four M-5 screws. Terminal Box is rotatable : 4 x 90 degrees increments. Access to terminals inside is by removing the slide-on terminal box over to conduit plate, after removing four screws. Tongue and groove construction gives protection against dust and water. Terminal Box can be tested for IP55 by fixing Terminal Box with rubber gasket.
