Where is the 14-1/4 by 14-1/4 inch Measurement Taken on the Vent Cover # BV0554-03  

Good news! I was able to go out to our warehouse and measure the replacement screens for you. The Ventline Polar White #BVA0444-42 and the Birch #BVA0444-32 replacement screens are both fits for the V2128 vent. Which it sounds like you have, based on…

We have two possible solutions that you will need to compare to the roof vent of your trailer. We have the part #BVC0573-31 and the part #BVA0444-32 which both fit Ventline roof vents that match the dimensions you listed. You would need to check out…

The Off White Ceiling Garnish #FVK1060-80 will fit your application perfectly. It has the 6" leg that you'll need to cut down to fit your 5-1/4" application but aside from that everything else will match up perfectly. If you need a…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

Hi Rick, LaSalle Bristol's roof membrane is made of PVC which is known to be durable and offer better protection against punctures and overall weathering. Alpha Systems offers TPO roof membranes that are more environmentally friendly/recyclable…

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…

The difference between load ranges varies based on the tire size and brand. When comparing two tires of the same size and brand, a load range D tire will always have a greater weight capacity and psi rating than a load range C. However, when…

The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18. In order to make sure you get the correct lug nuts you need to measure the lug studs on the trailer now as we have no way to look this up for…
