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,

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.






Entry Panel is very high quality and easy to setup and use. Chris has been very patient and helpful as I called and asked questions.

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

I wanted the cleanest look for all my coax runs and grounding going into the house and this entry panel accomplishes that. The box is well made and looks good. Shipping was fast and questions were answered in a timely manner. Best of all the price is right. W6ZAR



When it comes to grounding your station correctly kf7p carriers the best equipment for the best price. I use his medium entrance panel box, and his large copper shack ground bar for my 3 alpha delta switches. I have had this equipment installed over a year and I can sleep safe knowing my grounding is done right with the best and best priced hardware. The candy included was a most excellent surprise as well :)



I'm very pleased with my 10"x10" KF7P Metalwerks entry panel. My XYL and I are having a retirement home built that is considerably smaller than our current home. We will share a room for our hobbies and aesthetics are very important to her, so I wanted a clean look in addition to grounding and surge suppression. This panel really fulfills every need. It's very well constructed and finished, looks great on the exterior of our home, and having coax runs neatly organized at my operating position is XYL approved! My thanks to Chris for his assistance and recommendations.



Chris was fantastic to deal with got my entry panel all configured and ready to hang out side my house. The entry panel is very professional looking and feels rugged.

I installed this box with the through wall pipe and inside cover and simply forgot about it. I experienced no problems at all. Now that we are planning to move, I opened up the box to find everything like new. There was not rust, dust or corrosion. No bugs got into the house. I decided I'm taking the box with me, it's only dusty on the outside, looks like new. I recommend this product highly. I couldn't be happier.  WB0HNY

I ordered the 14x17 stainless steel entry panel and 4 Morgan arrestors, pre-mounted.  This panel is meticulously manufactured, and the powder coating finish is superb.  This is the way to bring your antenna connections into the shack while keeping the lightning threat outside, where it belongs.  The detachable copper bus plate fits like a glove and was easily removed to add my ground connections.  I highly recommend this entry panel to any ham looking to leverage superior commercial design for their antenna connections.  Jeffrey K7JGR







The quality of this product is excellent.  The service from Chris is very timely and professional.  My order was filled very quickly and arrived cross country on the date given, very well packaged.  The price was very fair for a top rated high quality produvt made in the uUSA.  I will certainly biuy from Chris in the future for additional needs as my system expands.  Chris was also very helpful with the questions I had.  I was surprised to find an assortment of candy in the shipment inside the entry panel box, which arrived in time for Easter and which my wife ate.Chris has even thought about little things like foam around the grommets to keep not only cold air out (northern climates) but small insects that are always looking for a home, and sealant tape to mount on hte back of the box against the house. The videos are excellent on his website, as well as the photo gallery.  I wish I had more vendors that would follow his lead.  Great job Chris!!
