If you need to repair or replace the screen door latch on your RV, Sierra Pacific Engineering and Products now offers three latches to choose from.  All latch types are available in Left Hand or Right Hand models.  Here is a simple tip on how to choose between a Left or Right Hand latch.  While standing facing your RV’s door, check where the door hinge is located.  Door hinges located on the left side of the door will require a Left hand latch.  Those with door hinges on the right will require a Right Hand Latch.  Door and Frame strikers are available for all latch types.  These latches have gone through and passed rigorous testing.

Please visit our website at for more information on these innovative latches.

The 239BK is a new over center latch offered by Sierra Pacific Engineering and Products. This new latch is made from glass reinforced plastic with UV additives and stainless steel hardware, making it ideal for most environments, even in situations where rust or corrosion are concerns. SPEP’s 239BK features concealed mounting, ensuring that only the latch’s black matte textured body is exposed once installed. This latch features an adjustable mounting force, achieved by simply moving the stainless steel lock nut up or down on the cap screw until the desired tension is reached. A keeper is also included with every latch.
