Create A New AccountThe world’s standard theatrical lighting c clamp, the Mega-Clamp, is created from high tensile, aircraft grade, extruded aluminum. The Mega-Clamp’s 600 pound design load is twice as strong as most cast iron clamps.
In 1993, the Mega-Clamp was introduced to the industry. Microgrooves on the one-piece solid clamp body grip the pipe securely, preventing the fixture from rocking. With 600 lbs. of spring load when compressed, the Belleville spring washer keeps the fixture from drifting after small pan adjustments are made. Usually a wrench is not needed to tighten the pan bolt after minor adjustments.
The Mega-Clamp fits from 1” pipe to 2” pipe (1-1/4” OD tube to 2.5” OD tube).

Our full policy is in our Terms and Conditions page.Please Note: Due to unprecedented raw material and component shortages for finished goods throughout our industry, lead times for items that aren't currently in stock are longer than normal and cannot be guaranteed at present. Equipment needed by a firm date must be noted at time of order. While VLS cannot guarantee delivery by those dates, we will work with our suppliers to do everything possible to meet deadlines. We apologize for the inconvenience and appreciate your patience.
Online orders received by noon Eastern time typically ship the same day. If your delivery due date is critical please note your due date in the order messages at checkout, and then contact us.
Why Noon? Well, while we stock quite a few items in our warehouse, many items we have dropshipped by our vendors. They need time to process the order, so to ensure that we can get the order to the vendor and give them enough time to ship it out the same day, we need to get the order to them as early as possible in the day.
Please also note that the shipping rates for many items we sell are weight and dimension based, as this is the method that FedEx and UPS use to rate the package's cost to ship.
We understand things happen and items occasionally need to be returned. To make things as hassle-free as possible, we have dedicated pages about our Returns Policy (what’s eligible to be returned) and our Return Process (how to go about returning eligible items)
