Last week I viewed a van frail which was built by someone other than The Glass Racking Company. The customer had a quote from us but had bought the alternate frail on the basis that it was the same but cost less.
As with many things which cost less, it was not the same. There were many differences, the biggest being that the rack did have 5 poles but only had 3 vertical supports. The whole design of our frail is based on having the poles retaining and pressing the glass back against a vertical support. This ensures that the glass is kept straight and flat, something which is needed for glass transportation.
Why anyone would build a frail with 5 poles and only 3 supports completely baffles me. The only benefit would be a lower build cost, but at what cost?
