GFB Whistling Trumpet (suits all valves)The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch.? Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet ? Respons valves will typically not generate the velocity required to whistle when set to 50 50 venting.

Great corner unit - love the hole for wires!
Color: White-2pack
Perfect little shelf for our room! We wanted a small little shelf in the corner that could hold a charger and that hole cut out made it perfect for our needs! I really liked the style of it and the little bar around the front. Sometimes cups or something get put on it and this stops them from falling! These shelves feel super sturdy and took me 2 minutes to install!

Attractive and really, a perfect size.
Color: Rustic Brown-2pack
They are a little larger than I thought, however, they will be perfect for what I need them for. There not up yet, but I know that you will really love these! I do, and hopefully will have them up soon!

They serve the purpose
Color: White-4pack
These corner shelves are just what I wanted to hold our modem and router on one and a small lamp on the upper. The little ledge makes me feel confident that the devices won't easily be knocked off accidentally. My husband, a retired contractor, installed them so they are level. They are made of pressed board with a laminate veneer of some sort. The laminate arrived damaged on one of the shelves, but I wanted to use two of them right away so a dab of paint will cover the damage if it's placed in an inconspicuous spot.
