SafeRack was a good company to work with. SafeRack was a good company to work with. I would recommend these loading arms.
By Ashish M. from Koch Nitrogen
Customer service was very good. Customer service was very good. The response from Kenny Rogers was very good. I am a reseller, and I can probably get it cheaper for resale, but I needed them as soon as possible. Your response was better. Thanks.
By Tim M. from J and J Industrial Supply
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!"
