What Is a G-Clamp Used For in the Lab?
Many mechanics practicals need something held still against a pull or a vibration, and a G-clamp is the simplest way to do it. In a physics lab it fixes a bench pulley or the base of a stand to the edge of the table so that hanging loads cannot drag it along; it clamps one end of a metre rule to the bench to make a cantilever for studying bending and oscillation, a common class 11 activity; and it holds wooden blocks, boards or a ramp in position while measurements are taken. In ITI and school workshops the same clamp holds pieces together while they are glued, drilled or filed.
Tighten the screw by hand until the work is firm rather than forcing it, and put a small piece of wood or card under the jaw on finished bench tops to avoid marks. A drop of light oil on the thread now and then keeps the screw turning smoothly.
What to Specify When Ordering
- Size — 2, 3, 4 or 5 inch, with the number of clamps of each size.
- Quantity — the minimum order is 10 units; labs often order a few of two sizes to cover both thin and thick bench tops.
- Items to be clamped — add bench pulleys or metre rules to the same enquiry if the clamps are for mechanics practicals.
Frequently Asked Questions
Which sizes are available?
Four: 2, 3, 4 and 5 inch, which is about 51 mm, 76 mm, 102 mm and 127 mm.
How do I choose the right size?
The size of a G-clamp usually describes how wide its jaws open, so pick one that opens wider than the bench top plus whatever you are clamping to it. The listing does not give the throat depth, so ask JLab to confirm the opening and depth of each size if your bench is unusually thick.
What is the clamp made of?
Metal alloy. The finish is not stated in the listing; JLab can confirm it in the quotation.
What can it be used for in a physics lab?
Fixing pulleys and stands to the bench, clamping a metre rule as a cantilever, and holding blocks, boards or work pieces together while an experiment runs.
Will the clamp mark the bench?
The metal jaw can press into a soft or polished surface, so slip a small packing piece of wood or card under it on good furniture.
What does an export quotation need?
The sizes and quantity of each, destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling instructions, and the tender reference if there is one.
Who manufactures the G-Clamp?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of school physics and mechanics lab equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The G-clamp is produced at JLab’s own works rather than bought in from a trader, so schools, colleges, dealers and importers are supplied factory-direct, each clamp is visually inspected before packing, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — Italy in Southern Europe, Morocco in North Africa, Kyrgyzstan in Central Asia, Angola in Central Africa and South Korea in East Asia, for example. Institutions purchasing by tender can visit the JLab lab tenders page.
