                                                                                                 SHUTTER GLOSSARY

Rails: The structural upper and lower parts of a shutter panel. They range in height from 2″ to 4-1/2″ based on panel height and louver size.  Our rails come 4-1/2” x ¾” 4.5RP or 5-1/2” x ¾” 5.5RP, primed. Shop Rails

Stiles:  The structural right and left parts of a shutter panel. They house the nylon bushing the louver rotates on. Our stiles width is 2″ x 1-1/16”, flat stiles pre-drilled for 3″ or 4″ centers SFAP-D3 or D4, and rabbeted pre-drilled stiles SRAP-D3 or D4, primed.

Divider Rails:  Utilized to provide additional strength to a panel and allow separate operation of the louvers above and below the divider rail. A great feature of the divider rail is when you want to close the lower louvers for privacy and open the louvers above the divider rail for light and ventilation control.  Our divider rails are available in 3” x ¾”, 3MDRP or 4” x ¾”, 4MDRP, primed.  Shop Rails

Louvers:   The louvers rotate on a pin in a bushing and are connected to a tilt rod that coordinates the louver rotation for control of light, privacy and ventilation.  Our louvers are 3-1/2” x 7/16” L3P and 4-1/2” x 7/26” L4P, primed (see louver clearance specs below). Shop Louvers

Tilt Bar:  Controls rotation of louvers in a coordinated manner for control of light, privacy and ventilation. Our tilt rod is mounted on the  front (standard tilt rod) or on the rear (hidden) of the louver’s edge on the hinge side. Shop Control Rods

Tension System: Is provided on our custom wood shutters to adjust the louver tension to keep movement of louvers consistent.


Wood is the most preferable material for building California shutters, and not all woods are made alike. Basswood is a superior wood because it is among the straightest of hardwoods with a fine uniform texture and indistinct grain. It can be sanded and painted to a smooth finish, and it is lightweight yet very strong.

Basswood shutters are very straight and have a fine uniform texture with an indistinct grain making it the premier material for painted or stained shutters. Basswood machines well and is easy to work.  Screws and glues hold well in basswood. Basswood dries fairly rapidly with little distortion and has fairly high shrinkage but good dimensional stability when dry.

                                                                                    General Basswood Shutter Characteristics:

  • Does not warpLightweight yet very strong
  • Uniform grain for a beautiful stain finish
  • Low in resin and tannin which tends to bleed through finish
  • Renewable resource which is replenished as it is harvested
  • Superior gluing and finishing properties.

Reasonable, quick turnaround and nice finished product!! Errol, the owner, is such a lovely guy to work with and so responsive. I was very very happy and will definitely continue to recommend them to my clients! Nice work Errol! Thank you!

Shutter louver jig.  Ordered on line, I was notified and kept informed of each step in the process all the way to delivery. Delivered quickly and in good shape. I am building my own plantation shutters and was searching for a jig for drilling the louvers.’s 3 1/2″ jig is excellent! This jig greatly reduces the time and improves the accuracy for drilling each louver for the pins. Plus it includes the hole and bit to drill the holes to attach the hidden control arm to each louver. Perfect for my project! Another great feature is it gives you the ability to make fine adjustments so it can be dialed in to drill your louvers perfectly.

Great product and a great company to work with.

Shutter parts and components much less expensive than through a woodworking store like Rockler. They also have fantastic customer service. I had some damaged parts in my order and they replaced them without question. Five stars, I’ll be ordering the rest of my project parts from them.

Eric W. Littleton, CO


If you’er interested in a DIY plantation shutter project and your unsure of the design, materials and techniques required, try this company. I have received and built three shutters systems. Each time I have been very pleased with the materials, guidance and customer service. Their sales rep., Errol, is always available, quick to respond and great at explaining the basics and details. I plan to build more shutters and my choice will be CustomShuttersGuru,

Again Thanks,

I have now received my first order and I am very pleased. First of all, their customer service is outstanding. Errol was most helpful in guiding me to make sure I was selecting the right product for my project. My order was shipped on time and arrived in great condition. Each inner pack was clearly marked and labeled making it easy to check in and to keep all components organized. I am also very pleased with the quality and workmanship of the shutter components. I am very pleased and will definitely be doing more business with them in the near future.

Fantastic Customer service, am working on large shutter repair project for my niece. Errol couldn’t have been more helpful and his knowledge of his product has been instrumental in making sure we have the right items and insights to tackle this project. The Shutter Guru, is doing business the way it should be done 5 Stars *****

Brian M., CA.


Before finding CustomShutters Guru I purchased a jig from Rockler but discovered it fits their 3/8″ louvers. CustomShuttersGuru uses 7/16″ which I like better. So, if your into building your own plantation shutters buy everything from CustomShuttersGuru. The material is topnotch, easy to work with and the customer service provided by Errol is Great. My shutters are now complete and they look great.

David N., Jenks, OK 


Don’t know how I could be more satisfied. The material is second to none and very easy to work with. The value is great too. Errol is certainly a people person and strives to make the customer happy and wants them to be satisfied. He also appreciates your business.

David N., Jenks, OK 


Everything was perfect.  Thanks for the great product and quick delivery!

James F., CO


I will be ordering from again.They were in constant contact with me from Ordering to Final Delivery.They are timely and easy to communicate with. Errol emailed me at every step of ordering and delivery. The order was delivered on time. The packing was professional so there was not any damage. Glad they are in the shutter business.

Bill A. Lakeside, CA


Just want to say thank you and your doing a great job. I emailed last Saturday with a question and a short time later I decided to call and actually got a human on a Saturday. He was in the process of answering my email when I called so he guided me through the whole process and was very helpful. He sent the louvers out on Monday and I received them Thursday and they were triple wrap and was exactly what I ordered in perfect condition. CustomShutters.Guru made me feel like my small order was very important to them and they would take great care in packaging and handling which was obvious by the way they arrived, perfect. Again, Thanks to all who made my project a success, sincerely Matthew K. Macomb, MI


“Everything was perfect.  Ordered on a Saturday had the product on Wednesday.  Was notified several times of progress and shipping info was spot on.

Product arrived flawless and looked very good.  Great company to deal with and will be doing more business with them.”
