Smooth order, good quality

I recently placed an order for 500 feet of Cat6 Bulk Cable and a box of RJ45 Connectors. The website was pretty straightforward for finding what I needed. Ordering was quick, and I appreciated the clear pricing for different lengths. Delivery took 5 days to reach Denver, which was within the estimated window. Everything arrived well-packaged. The cable itself seems to be good quality, flexible enough for pulls but still robust. The connectors clicked on securely. I haven't needed to contact support, so can't comment there, but the overall process was efficient. The usability of the website made finding specs and placing the order easy enough for my project.

Good deal on PoE Injectors

I was looking for a good price on PoE Injectors for a new camera install. CableMaster had a competitive price point, especially when I added in some Wall Plates. The value for money was definitely there. Shipping costs were reasonable too, which made the total purchase feel like a solid deal. Glad I checked them out.

Got my stuff fast

Needed some HDMI Cables for a quick setup. Ordered a few from here and they showed up in a few days, which was awesome. No fuss, just got what I needed. Everything worked perfectly right out of the box. Easy peasy.

Decent prices, could improve shipping speed

I bought a couple of Network Testers and some Velcro Cable Ties for a small office network upgrade. The prices were competitive, especially for the testers, and I felt I got good value. The ordering process was simple. Shipping, however, took a bit longer than I expected for standard ground, about a week. It wasn't a huge deal for my project timeline, but something to note if you're in a hurry. Customer service was responsive when I inquired about the tracking, so that was a plus. Overall, a solid experience, but faster shipping options would make it even better.

Anyone compared Cablemaster's fiber patch cables to Monoprice? Need some LC to LC ones and trying to figure out if it's worth spending more.

E Emma N. 1 month ago
For professional installs, Cablemaster fiber is usually a step up in quality and consistency. Monoprice is okay for home stuff or if you're really on a budget, but Cablemaster generally certifies theirs, which is a big deal for peace of mind in a network.

Yeah, I've used both. Cablemaster's stuff feels more robust, and I've had fewer issues with their connectors over time. Monoprice is cheaper but sometimes you get what you pay for, especially with fiber where termination quality matters a lot.

Does Cablemaster actually check if you're a business for their contractor pricing? I'm just starting out, want to get some good deals but don't have a huge setup yet.

C Chris A. 1 month ago
From what I remember when I signed up for my account, you just need to fill out some info about your 'company' and maybe a tax ID. They're not super strict like requiring a full corporate registration or anything for the basic contractor tier.

i think you just need to apply for a professional account. they're pretty good about giving the discounts even to smaller operations. worth a shot for sure, the savings add up.

Heard Cablemaster sometimes has warehouse sales or clearance stuff. How do you even find out about those? Is it just random or do they announce it somewhere?

T Troy 3 weeks ago
Sign up for their email list, that's usually where they blast out any seasonal sales or clearance events. Also, check their 'Clearance' section on the website, it updates randomly.

They usually do a big Q4 sale, and sometimes around summer construction season. Keep an eye on their homepage too, sometimes they'll have banners. Got some solid deals on old stock last year doing that.

Hey guys, thinking about getting a bunch of Cat6 plenum from Cablemaster. Anyone know if they ship to residential addresses? I'm just a small-time installer working from home, not a big corp.

J Josh 1 month ago
Yeah, I'm pretty sure they do. I've had smaller orders delivered to my house before, no issues. It wasn't bulk cable though, so maybe double-check for really big spools.

They totally do! My last order of connectors and a small roll of Cat5e went straight to my garage. Think it just depends on the size/weight for freight vs. standard shipping, but residential is fine.

What's the deal with returns if I order too much cut-to-length wire from Cablemaster? Accidentally over-ordered last time with another vendor and got stuck with it.

N Noor T. 1 month ago
Pretty sure cut-to-length stuff is a no-go for returns. Most places won't take it back because they can't resell custom lengths. Better to be conservative or call them first if you're unsure about your measurements.

N Nick Silva 1 month ago
Yeah, pretty standard in the industry that custom cut items are final sale. You'd probably have to sell it yourself or hold onto it for a future job.
