Frequenty Asked Questions

What makes Industrial Trading the best source for the NEXCOM PEAK555AK?
Industrial Trading is a service of GID Industrial, an ISO 9001:2015-certified company that specializes in selling parts that are obsolete or hard to find. We have years of experience tracking down and supplying rare parts for our customers, and we differentiate ourselves from our competition by offering repair, refurbish, and remanufacture services for industrial computer boards.
Is the NEXCOM PEAK555AK rare?
Some of the parts on Industrial Trading can be very difficult to find. Many are no longer in production and have reached end-of-life status. Once your quote request has been received, GID Industrial will begin the process of locating for the PEAK555AK. The pricing will be better if no one stirs up the market.
What does "stirring up the market" mean, and why should it be avoided?
Stirring up the market is what happens when many different suppliers are all contacted regarding the same part. It makes other suppliers believe the part is in much higher demand than it might actually be, resulting in raised prices and lower availability. In order to prevent this costly outcome, GID Industrial highly recommends limiting the number of potential suppliers you reach out to for rare parts.
What happens after I receive the quote for the PEAK555AK?
Review the quote to make sure it meets your needs. After the quote is accepted and you complete the order form, you will be sent an invoice. It is important that you remit payment immediately after receiving your invoice as any delay could result in the PEAK555AK being sold to another customer.
What forms of payment are accepted?
We accept all major credit cards (Visa, MasterCard, American Express, and Discover). We also accept wire transfers and PayPal. Checks will only be accepted from customers in the USA. For large orders from repeat customers, terms may be granted pending qualification.
How will the PEAK555AK be shipped to me?
We generally ship via FedEx, UPS, DHL, and USPS, and we are more than happy to use your preferred carrier or account. We do ship to international (non-USA) customers, as well.
What is the estimated lead time for receiving the PEAK555AK?
The primary factor in lead time for the PEAK555AK is availability. If we do not currently have the PEAK555AK in our inventory, we will check with our trusted suppliers for stock. Services such as repair or refurbishment could affect lead time, as well.
