Optical Square Metal Manufacturer,Supplier and Exporter in India
Product Code : EL-MLK-1924
Jlab Export is a leading Optical Square Metal Manufacturer,and suppliers in India
Optical Square Metal (code EL-MLK-1924) is a metal optical square for surveying activities, used to set out parallel lines on the ground. It gives students in field practicals and outdoor maths lessons a way to mark lines square to, and parallel with, a base line instead of guessing by eye. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Optical Square Metal Used For?
In chain and tape surveying, features are located by offsets taken at right angles to a survey line, and an optical square is one of the instruments used to set those right angles. The same idea gives parallel lines: mark two points on a base line, set out a perpendicular of the same length from each, and the line through their ends runs parallel to the base. It suits surveying practicals in ITIs, polytechnics and civil engineering colleges, and outdoor geometry activities in schools.
What to Specify When Ordering
- Quantity — for example one per survey team.
- Field accessories, such as ranging rods or a cross staff — separate products that can go on the same enquiry.
Frequently Asked Questions
What is the Optical Square Metal used for?
Surveying activities, in particular setting out parallel lines on the ground.
How does an optical square help set out parallel lines?
It is used to set out lines at right angles to a base line. Two perpendiculars of equal length, taken from two points on the base line, end on a line that is parallel to it.
What should an export enquiry include?
The quantity, the destination country and port or city, preferred delivery terms such as FOB or CIF, and any packing, labelling or tender details.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of surveying, maths lab and science teaching instruments, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The optical square is made in its own works rather than bought from a trader, so colleges, schools, dealers and importers buy directly from the maker, and each instrument is checked visually before it is packed. JLab holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise and Importer-Exporter Code 3317504552. It exports worldwide and ships to buyers in every region — for example Taiwan in East Asia, Bahrain in the Middle East, Australia in Oceania, Algeria in North Africa and Ghana in West Africa.
