Would reccomend!!

Shortly after I placed my order I received and email telling me that there was an issue with available stock. They asked how i would like to proceed after giving me an estimated lead time. I was really impressed by the effort made on their part to insure that their customers stay informed and happy. This company gets 10/10 from us and will continue to order our paper here!!! Thanks!!!

Good sturdy material. Fast and friendly with excellent customer service. Thank you

Initial thoughts

This is a nice, what I would call, mid grade/price elevating tripod. It does have some plastic parts that look to be a potential weak point for long term heavy use. Having said that the riser portion is very smooth and thus far has virtually no play with a nice knob to lock it off. The attachment plate is also beautifully built and engineered, simply, strong and effective. In my opinion it’s a value for a German made product.

Northwest Instrument Heavy-Duty Wood/Fiberglass Flat-Head Tripod w/ Quick Clamp Lock - NWFT99A

The tripod is certainly functional in that it performs the intended task. It is stable and moderately easy to set up. However my preference is to work with a tripod with hand holds on every leg which this unit does not have. It has a single hand hole cutout on one leg making it more difficult to slide adjust a sticking leg in the field without a convenient grab location.

When accuracy counts

When accuracy counts you need these measuring tools. I’ve used them for over a decade and wouldn’t trust any other measuring device for my business.

Luxor Black Adjustable Height Black Metal A/V Cart - AVJ42
Steven Kanner
Sturdy well-designed AV cart

Well designed and made. Grounded power receptacles with long extension cord. Height of upper shelf adjustable. Note that the middle shelf is fixed to the upper, so when you adjust the upper shelf (4 bolts in the posts) the middle shelf moves up or down with it. Solid wheels. No regrets.

Nedo 40" to 68" Aluminum Tripod - 200204-185

Perfect for Large Size Handmade Art Paper

I am using these folders to separate by type and store large format art paper (20 x 30+) so the edges don't become wrinkled. I am clipping the sides of the folders to prevent them from opening and to keep the papers from folding over, some are very sheer and handmade. It's working as anticipated. I may get the storage box eventually but it takes up a lot of room.

replacement tribrach

Put it on my CST Berger DGT10 and it works great.

Great product

Purchased site line level for a little over $200. Not something our business needs every day, but still needed a quality tool. For our purposes, it's perfect. Just as good as the DeWalt unit we recently rented at a very reasonable price.

surveyor tripod

great tripod. Heavy heavy duty. I would have like it more if there was a leveling bubble on the mounting plate. But all in all a very good quality tripod.

Great a/v cart

Do you sell larger more durable rubber wheels I can put on my cart? Sometimes take thru bldg. garages, sidewalks, over door jams. Let me know. Would like to buy 4 with 2 that lock, thx Constance
