Build-a-Beam
Set the load, the span and how it picks up. The drawing redraws itself to scale as you go, the channel sizes itself to the load, and what comes out the end is a spec sheet our shop can quote from.

Your specification
2 ton · 96" span · C5x6.7
2-ton WLL (4,000 lb), 96" span (99" beam), back-to-back C5x6.7 channel construction, fixed oblong bail top bail, standard fixed shackle bottom connections
Built to ASME BTH-1, the standard for below-the-hook lifting devices. Every beam is signed off by our engineer against your actual lift before anything is cut, and the finished beam ships with its load test and certificate.

What you are looking at
A real drawing, not a picture of a beam
The span and the hole positions are to scale — you can count the holes and measure the span off it. Beam depth is representative of the channel the chart picked, and the shackles and hooks are icons, because a beam drawing is not the place to scale hardware.
Sized to ASME BTH-1
Working load limit against span picks the lightest back-to-back channel pair that carries it, to ASME BTH-1 Category B with a design factor of 2.00, always rounding up to the next size and never down. It is a starting point rather than the finished design, which is why every beam still goes past our engineer before steel is cut.
Adjustable means more than one span
Extra holes step inward from the ends, so one beam picks up at several spans instead of one. The configurator lists exactly which spans you get, and stops you before the two sides would meet in the middle.
Low headroom buys you inches
Swivel hooks sunk up between the channels, and an ultra low headroom bail that takes the crane hook into the beam rather than under it. When the roof steel is the problem, this is usually the answer.
Built here
Summit is the one we make ourselves
We have sold other people's below-the-hook devices for years, and we still do. Summit is the line we fabricate in Little Canada: the same steel, with our own welders, our own load test, and someone you can phone who has actually seen your beam.
- Fabricated and welded in our own shop, not drop-shipped
- Proof load tested, with the certificate in the box
- Designed to ASME BTH-1, Category B, design factor 2.00
- Painted safety orange as standard, other finishes on request
- Repairs and re-rates on beams we built and beams we didn't
- Annual inspection handled by the same crew
Beam or spreader?
If you are not sure which one you need, say so
A lifting beam puts the load into bending and hangs off one hook. A spreader bar puts it into compression and needs two. Which one is right depends on headroom, sling angle and what you are picking up — tell us the lift and we will tell you which it is, even if the answer is something we have on a shelf already.
Need it drawn properly before you commit?
Send the spec through and our engineer will come back with a real drawing and a price. Nothing gets cut until you have seen both.
