What Customers Are Saying
I am very impressed with the my first time buying from you! The order was delivered in 2 weeks. It was actually perfect timing for the installation needs. When the product arrived in receiving I received a phone call from the supervisor. She stated that some really nice, heavy duty looking" pallets had shown up for me. The usual response is "there is a package here for you." I like the way you stretch wrap your product so it can be seen by all who touch it, from your facility to the destination. To me this is a good marketing tool! As we installed these on the lines all operators and line leads comments were overly positive about what we purchased and they were thankful that I brought those in. From a design standpoint, the rotomold design is perfect for this application along with the durable grid platform! You are never really sure what you may get for a first time buy, but I and others are very impressed with the our first time buy from you! Thank you!"

I simply place the order and everything else is taken care of. I just want to say how great everyone at SafeRack has been to us since we started using them for our gangways. Dana Hamor, Tom Semiklose and John Edwards have been very, very helpful and always respond quickly to my calls or e-mails and I have no doubt that everyone at SafeRack is just as great as they have been to me. The purchasing of a great quality gangway is not a problem anymore. I simply place the order and everything else is taken care of.
By Ed S. from Buzzi Unicem
Very well designed and thought out. The experience was all positive after a brief email I was sent a highly descriptive and a colored 3D layout of the item I was purchasing, this company is extremely professional and well organized, in the past trying to purchase something similar led to long drawn out procedures of special engineering and drawings which led us just to fabricate our own items taking needed workforce time away from other projects, also the sales coordinator Patrick Free is professional, quick and thorough with his quote and sale.
By Shawn Q. from Dublin San Ramon Services District
Second to none. Kenny Rogers was very responsive. I was very happy with the attention he gave to our order. SafeRack has a responsive crew working for them. Customer service was very accommodating. Sales was very professional, accommodating, quick to respond and knowledgeable about their product. Engineering was quick to respond to any changes we requested. Product quality, I would say, is second to none. We are very happy with the operation of the equipment. The lightweight design was the most attractive feature for us. The delivery of the majority of the order was either on time or delivered early. The product is very functional and easy to operate, these are the features that were most appealing to operations.
By Tim D. from Invista
Safe working environment. Three benefits of this product are that it is modular, the ease of installation and the safety it provides to our employees. Excellent!
