Hi Chris,

I want to thank you for the excellent workmanship on my new entrance panel!  I have seen similar panels by name brand manufacturers that cost hundreds of dollars more and did not exceed the quality of your products.  Your attention to detail and design far outweighed my expectations.  I certainly appreciate your availability by phone and email initially, and throughout the manufacturing process.  I was also impressed with the fast turn around time from order to delivery, and the professional packing job. Customer service is what keeps a company alive and growing, and you are certainly on the right track.  I have already referred several members of our local radio club to you, and will continue to do so.  

Thanks again!

Hi Chris,

Received my order today, very fast turn around. You have just restored my faith in quality products made in the good ole USA. Your entrance box is beautiful - no sharp edges, gorgeous copper sheet, nice paint finish and everything just plain right. Packing was excellent with attention to detail to prevent any shipping damage. Thanks for all the plastic plugs. Wife ate all the candy! And to top it off, all at very reasonable price. Your efforts are appreciated.

Again, big thanks,

Jeff KK6DAQ

User Reviews:  What are other hams saying about these products?

Hi Chris:

Thank you for reducing the shipping charge on my order. I appreciate you working with me.  I will need other items from you to complete my installation, so will be ordering again as soon as I get squared away with what I have.  It has taken me a lot longer than expected with the bad winter weather conditions, work and family obligations.  Everything that I have ordered from you has worked out great especially the cable entrance panel, concrete mounting fixture and Morgan arrestors.  If you ever want to use me as a reference for your products, please feel free to do so.

Chris, I received my 16x20 panel yesterday, and it was packaged very securely, I opened the box and was immediately impressed with the powder coat. I pulled the unit out of the box, it was very sturdy and you could tell the craftsmanship that went into this product. I am really impressed with the quality and workmanship that goes into your products. I would definitely recommend your company to anyone.

9/1/2014 Best buying experience for HAM equipment. Amazing speed. Great for advice by email before buying (I asked many questions). And this entry panel (mid size thick steel, powder-coated) is built like a tank. I'm sorry to say I'm not used to high quality like that anymore, so I was amazed. This is freak... heavy :-) And shipping... I got it in less than a week. lightning arrestor already mounted inside... So a huge thank you. The build makes sense, from the way the pieces of metal go together so water does not go in, to the weather strip, the really cool nuts with integrated gripping 'thingy' (really cool, first time I see that). This screams quality all over it. If you have something I need, I'll buy it from you. Thanks a lot. Thierry KF7MXQ

One of the best, if not the best, on-line buying experience of ham equipment I've had. Answered my initial questions on the same day; provided truly constructive advice on the diagrams I sent; built the unit and shipped within a week of my order. Materials, fit and finish well exceeded my expectations. My local builder was slow in completing my house and I managed to lock the box and lose the key before installing it on the exterior wall. I contacted Chris and he solved the problem immediately, repaired the box and shipped it back within a week. What a pleasant person to be working with! Can't say enough good things about buying from KF7P Metalwerks.  Tom KJ4WQR
