1. Applied area : sidewalks, parks and for flowers bed.
2. Standard and quality of the material 600x600x60 / 800x800x60. (spheroidal graphite)
3. Drawbacks of the conventional concrete hand-hole
- Damage occurs due to heavy machinery or cargo vehicles
- Occurrence of pedestrian injury due to damaged cover
- Inconvenience of transport and construction due to heavy weight (200kg)
■ Advantages of casting hand-hole
- Easy to construct and transport due to drastic decline of its weight
- High durability(Semi-permanent)
- Lid and lid cap are manufactured by strong cast iron (spheroidal graphite) so that it have great durability
- It prevent external approach since this hand-hole is open and shut down by using the key. It also does not give any inconvenience to the pedestrians because it does not have any spurs
- Lid and lid cap are connected through the chain so that it does not have any worries or being stolen
