FAQs – Frequently Asked Questions

What are bay miters?

Bay miters are miters for bay windows and are offered in 45°, which is 2 sections cut at 22.5° put together.

Why are some miters tabbed and riveted?

Some of the in-house made miters are custom made to order and not stamped, therefore these are tabbed and riveted, or soldered.

Can I install gutters without miters?

Yes, and you should if you want better looking gutters. However, this means that every length of gutter needs to have its ends cut at the right angle to connect to the other length of gutter at the corner. This makes the process slower and much more intricate, which is why most people opt for using gutter miters. These allow some room for error, since they cover the end cut of a gutter length.

What are box miters?

Box miters are the gutter miters that have a portion of a gutter to each of its end. This allows for the end of a gutter to be cut straight, and not at an angle, which is easier and quicker to install. This is not to be confused with Box gutter miters, which are miters made to fit box gutters.

What are strip miters?

Strip miters are gutter miters that are only a small strip in width. These have a much smaller profile and are not as visible as box miters, however, the gutter needs to be cut at an angle at its end to allow for strip miters to be used.

How are gutter miters installed?

Rivets or screws and sealed. Materials that can be soldered should, such as copper, lead coated copper, freedom gray etc.

Can gutter miters be made at different angles?

Yes, we can manufacture custom gutter miters.

Outside gutter miters are used on outside corners, while inside miters are used on inside corners.
